For accurate, repeatable, real-time transmittance measurement of optical lenses and other optical components, Ocean Optics (Dunedin, FL) 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. The OTS is built on a high-resolution miniature linear CCD-array 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 to ±0.1% are critical.
