準直透鏡：三個熔融石英透鏡（200-2000 nm）

光纖接口：SMA 905

尺寸：111毫米x 90毫米x 74毫米mm

重量：618 g

光程：1 cm

濾光片槽：兩個，可接受直徑為12.5 mm或25 mm的光學濾光片。

熒光配件：反射鏡（74-MSP）以增強熒光信號；鐵氟龍漫反射境（CVD- DIFFUSE）以增強熒光信號。

Largo, Florida, USA (March 1, 2019) – Ocean Insight, the applied spectral knowledge company, has introduced a convenient, manageable cuvette holder for highly accurate, repeatable absorbance and fluorescence measurements. The Square One cuvette holder has three collimating lenses with fiber optic connectors, is designed with an integrated cover to reduce ambient light, and provides a snug, reliable fit for cuvettes and filters to ensure best results.

Square One accommodates 1 cm pathlength plastic or quartz cuvettes. Its built-in mirror optimizes signal reflection for fluorescence, while two filter slots accept both 12.5 mm and 25 mm diameter optical filters. With filters, users can manage fluorescence excitation and emission wavelengths or remove unneeded wavelengths to reduce stray light.

At just 111 mm x 90 mm x 74 mm (4.4 in. x 3.5 in. x 3.0 in), Square One takes up very little bench space. It has a black, hard-anodized aluminum interior and base plate, with silver

Cerakote® body, for great durability. Square One integrates seamlessly with Ocean Insight spectrometers, light sources and optical fibers for flexibility in cuvette-based measurements.
