Display manufacturers and optical engineers often struggle with accurate viewing angle analysis. Standard lenses and cameras cannot precisely measure luminance, contrast shift, and color variation across wide angles.
This creates challenges in LCD, OLED, and microdisplay quality control. Inconsistent measurement methods can lead to unreliable data, product rejection, or customer complaints. For B2B manufacturers, precise optical testing is critical for maintaining industry standards.
The Solution: High-Accuracy Conoscope Lens Technology
A high-accuracy conoscope lens provides accurate angular light measurement for display evaluation.
Unlike regular imaging lenses, a conoscopic system captures angular distribution information from a single point. This allows engineers to measure brightness uniformity, contrast performance, and optical anisotropy efficiently.
For manufacturers, it improves quality control accuracy and testing speed.
What Is a Conoscope Lens?
A conoscope lens is a specialized optical component used to analyze angular light distribution.
Key Characteristics:
- Wide angular capture range
- High optical precision
- Minimal distortion
- Uniform light mapping
- Compatible with imaging sensors
It is widely used in display measurement systems to evaluate optical performance.
How It Works
The lens collects light emitted from a display panel and converts angular information into spatial distribution on an image sensor.
Working Principle:
- Light from a display enters the lens.
- The lens maps emission angles into a measurable image.
- A camera or detector records the angular distribution.
- Software analyzes brightness and color consistency.
This method enables precise viewing angle analysis without mechanical rotation.
Problems with Traditional Measurement Methods
Older testing methods require mechanical goniometers or rotating measurement systems.
Common Limitations:
- Time-consuming rotation process
- Alignment errors
- Limited angular resolution
- Larger equipment footprint
- Lower measurement efficiency
These systems slow down production testing and increase operational cost.
How Conoscope Lens Solves These Issues
The conoscope lens simplifies angular measurement by capturing wide-angle data in one setup.
It provides:
- Fast angular mapping
- Reduced mechanical movement
- High measurement repeatability
- Compact system integration
- Improved testing efficiency
This makes it ideal for automated production lines and R&D labs.
