PRESS RELEASE

Optical Transmittance Spectrometer

Ocean Optics has released its Optical Transmittance Spectrometer (OTS).

The compact system measures tint colour, 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 CCD-array spectrometer configured for the 380 to 780nm wavelength range. The system accepts samples from 10 to 76mm diameter and 15mm thickness for use in lab applications where transmittance accuracy (to +/- 1.0 per cent) and precision (+/- 0.1 per cent) are critical.

A high-power, 20W 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 many 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.
