OTiS Optical Transmittance System

This simple, yet elegant system is ideal for accurate, repeatable measurements of optical filters, glass and ophthalmic lenses.

Weve combined our expertise in miniature spectrometers and accessories with experience as a manufacturer of precision optics to create a compact system for real-time transmittance measurement of ophthalmic lenses and other optical components.

The Ocean Optics Optical Transmittance Spectrophotometer (OTiS光学透射系统) is ideal for both in-line and in-lab applications where transmittance accuracy (to +/- 1.0%) and precision (+/- 0.1%) are critical. Common applications include measurement of optical coatings, windows and filters, and glass and plastic components.

About the System
The OTiS光学透射系统 covers the 380-780 nm wavelength range and accepts samples from 10-150 mm in diameter and up to 10 mm thickness. The system comprises several components:

• High-resolution miniature linear CCD-array spectrometer configured for 380-780 nm

• High-power, 20-watt tungsten halogen light source

• Fiber optic integrating sphere for collecting signal transmitted through the sample

• 光学透射系统Optics for improved beam collimation and spectral sensitivity distribution

• Sample fixture (z-stage) to hold sample in place and exclude ambient light

• Short optical fiber to channel signal from the integrating sphere to the spectrometer

• Customized lens transmittance and color calculation software
