Product Details
Lens Spectral Reflectivity Measurement Device
- Model：USPM-RU W
- Specification：Quick, highly repeatable measurements; detailed graph analysis
Product Introduction
Optical Metrology (USPM-RU W)
The USPM-RU W is a reflectometer that provides highly accurate spectral reflectivity measurements of small, curved, and thin samples without interference from rear surface-reflected light.
Features:
- Reduce light reflected from the surface
- Quick result
Applications:
- Individual types of lenses (Eyepiece lens, pick-up lens, etc.)
- Prismatic reflectivity and thickness measurement (Single layer film of mirror, prisms, or other coated components)
