Included with each holder are three collimating lenses with fiber optic couplings, integrated mirror to optimize signal reflection, built in cover to block ambient light and two filter holders that accept both 12.5 and 25 mm diameter filters. When used with Ocean Insight spectrometers and light sources, SQUARE ONE is ideal to measure absorbance, fluorescence, scattering or any combination of these optical phenomena.
Versatile design – configure holder for absorbance or fluorescence measurements
Dual filters – allows light to be filtered entering and/or exiting the cuvette holder
Integrated cover – protects photosensitive samples
Fiber optic – couples via SMA 905 connectors
Optical design – collimating lenses with adjustable focus
