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光學(xué)透射系統(tǒng)) 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光學(xué)透射系統(tǒng) 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
-
光學(xué)透射系統(tǒng)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
