Quality Management
FORESEEN OPTICS is committed to providing the highest quality optical rifle scopes, ensuring that our products lead the industry in optical performance, structural strength, and reticle accuracy. Below is an overview of our core internal quality management process, covering every stage from optical quality control to assembly error management.
| 1. Ensuring Optical Quality
Lens Precision Inspection
Lens precision is crucial to optical quality. Therefore, we conduct strict precision inspections during each stage of lens processing and assembly. We use high-precision interferometers to measure the lens surface shape, thickness, and curvature radius, ensuring lenses meet design specifications. Additionally, we use precise measuring equipment to inspect lens centration, ensuring the optical axis aligns with the mechanical center to prevent image distortion. Each batch of lenses undergoes rigorous random sampling to ensure product consistency. Every inspection record is meticulously documented and archived in our quality management system for traceability and analysis.
Lens Coating Inspection
Coating is essential for enhancing lens optical performance. We strictly inspect each coating layer for thickness and uniformity. Specialized equipment is used to measure reflectance, transmittance, and coating thickness, ensuring each lens meets the highest optical performance standards. Coating inspections are conducted in cleanrooms to prevent dust or impurities from affecting coating quality. After coating, every lens undergoes strict spectral analysis to ensure coating uniformity and performance.
Finished Product Collimator Testing
In the finished product inspection phase, we use collimators to test the optical system accuracy of rifle scopes. Collimator testing simulates the scope’s imaging performance in real-use scenarios, ensuring that the optical system is well-aligned and meets optical quality requirements. We conduct multiple imaging tests on each finished product to evaluate clarity, edge distortion, and field uniformity, ensuring compliance with optical design standards.
Inspector Visual Target Testing
Our inspectors are highly trained professionals who conduct final inspections of optical performance through visual target testing. Inspectors use different magnifications to thoroughly evaluate image quality, clarity, contrast, and distortion, ensuring every rifle scope meets high optical standards. Each inspector undergoes rigorous training to identify even the slightest optical defects, guaranteeing high product quality.
| 2. Ensuring Structural Strength
Material Inspection for Component Manufacturing
FORESEEN OPTICS conducts stringent quality inspections on each component to ensure it meets the strength requirements for rifle scopes. We test key materials, such as aluminum alloys, for hardness, tensile strength, ductility, and corrosion resistance to ensure stability in various environments. For critical components like housings and mounts, we conduct fatigue testing to simulate long-term stress conditions, ensuring material reliability.
Component Pre-Inspection
Before processing, we perform pre-inspections on all critical components to verify compliance with design specifications. We use quick fixtures and gauges for dimension fitting measurements, ensuring component precision aligns with standards. Pre-inspections effectively reduce the risk of dimensional deviations during machining, ensuring a smooth assembly process.
In-Process Sampling and Patrol Inspection
During machining, we have a rigorous sampling and patrol inspection process. Technicians perform sample inspections at critical stages, verifying component dimensions, surface quality, and geometry to ensure compliance. Patrol inspectors monitor the production site in real-time, addressing any issues immediately to maintain quality. Additionally, we monitor environmental factors like temperature and vibration during machining to ensure stable precision.
Impact Testing for Finished Products
To ensure the structural strength of rifle scopes, we conduct impact testing during the final product phase. Simulating extreme shocks, these tests evaluate the scope’s shock resistance. Multiple repeated impact tests ensure rifle scopes function under harsh conditions. All test data is documented and used for product improvement to meet customer expectations for robustness and durability.
| 3. Ensuring Reticle Accuracy
Reticle materials directly affect aiming accuracy. We conduct thorough inspections to ensure high optical transmittance and durability, meeting precision requirements. All materials undergo mechanical performance testing before storage to ensure consistent quality.
Reticle Transmittance Testing
Transmittance is a key indicator of reticle quality. We use photometers to test transmittance, ensuring that it meets design standards without compromising the overall optical performance. Transmittance testing is conducted under strictly controlled lighting conditions to ensure accuracy.
Reticle Etching Inspection with Microscopy
The etched lines on the reticle are crucial to aiming accuracy. We use high-power microscopes to inspect etching depth, width, and positional accuracy, ensuring every line meets specifications without deviation or defect. Microscopic inspection identifies even the smallest etching defects, ensuring each reticle meets high precision standards.
Reticle Corrosion Resistance Testing
Reticles may be exposed to various environments during use, making corrosion resistance critical. We conduct corrosion resistance tests to ensure reticles remain accurate under long-term exposure to environmental factors. Each batch must pass these tests to ensure stability under harsh conditions.
Cleanroom Assembly
Reticle assembly is conducted in a cleanroom to prevent impurities from contaminating etched lines and compromising optical precision. We strictly monitor cleanroom conditions, including air quality, temperature, and humidity, to ensure optimal assembly conditions.
Final High and Low Magnification Visual Inspection
After assembly, each rifle scope undergoes 100% visual inspection at high and low magnifications. Inspectors evaluate image quality, reticle line clarity, and alignment to ensure precision. We also assess imaging performance under different lighting conditions to guarantee aiming accuracy across various environments.
| 4. Assembly Error Control
Use of Work Instructions
Under the ISO9001 quality management system, FORESEEN OPTICS strictly utilizes work instructions to standardize each assembly step. Employees follow these instructions to ensure consistent quality, reduce human error, and meet specifications for each stage of assembly.
Stability of Key Positions
We maintain stability in key assembly positions, such as lens assembly, scope tuning, reticle installation, sealing, and final checks, by ensuring that these roles are handled by professionally trained and experienced personnel. Regular training sessions are held to keep employees’ skills up to date with the latest requirements, effectively minimizing errors.
On-Site Patrol Inspection System
To further minimize errors during assembly, FORESEEN OPTICS implements a strict on-site patrol inspection system. Quality inspectors perform real-time checks at the assembly site, promptly identifying and correcting any issues. Detailed records are kept for each patrol inspection for later analysis and continuous improvement.
100% Inspection of Key Positions
For key positions such as lens assembly, scope adjustment, reticle installation, sealing, and packaging, we implement a 100% inspection policy. Each product must pass comprehensive quality checks before leaving these key steps. Inspections cover optical performance, mechanical strength, and sealing to ensure high-quality output.
Quality Feedback and Improvement
If any quality issues are detected during assembly, they are immediately reported to the relevant departments for root cause analysis and corrective action. Each corrective measure is documented and tracked to prevent recurrence. Through continuous feedback and improvement, we ensure that every rifle scope meets the highest standards set by our customers.
With these comprehensive quality management processes, FORESEEN OPTICS ensures superior performance in optical quality, structural strength, and reticle precision for our rifle scopes. We maintain stringent quality standards, constantly improving and optimizing our processes to meet customers’ needs for high-quality optical products.
We also support third-party inspections and customer on-site audits and are willing to collaborate with experienced quality control personnel to produce rifle scopes that meet customer expectations.
