Optical Transmittance Spectrometer

For accurate, repeatable real-time transmittance measurement of optical lenses and other optical components, Ocean Optics has introduced the Optical Transmittance Spectrometer (OTS).

The compact system measures tint color, photopic transmittance and UV cutoff of ophthalmic lenses, optical coatings, windows and filters, as well as characterising photochromic, electrochromic and sun lens materials.

The OTS is built on a high-resolution miniature linear CCDarray spectrometer configured for the 380-780 nm wavelength range. The system accepts samples from 10-76 mm diameter and 15 mm thickness for use in lab applications where transmittance accuracy (to +/- 1.0%) and precision (+/- 0.1%) are critical.

A high-power, 20-watt tungsten halogen light source provides stable, continuous output. High-resolution optics provide beam collimation. The sample fixture (z-stage) holds the sample in place and excludes ambient light. Windows-based software calculates %T, colour, and other critical optical measurements to meet CE, UL, RoHS, WEEE requirements.

Ocean Optics Applications Engineers are available to customise the software with the modules required for application needs.
