Description: The Big Dipper, model RRDP, is a high precision, high throughput dip probe designed for use with fiber optic spectrometers. It features a compact design with a diameter of 0.5 inches and offers cost-effective sampling. The probe is available in UV/VIS or VIS/NIR versions, with typical optical efficiencies of 45% at mid-range and a numerical aperture of 0.32 NA. Constructed from robust materials like 316 CRES and fused silica, it is suitable for a wide range of chemical environments.

Features: The Big Dipper is utilitarian, highly convenient, precise, and robust. It supports path lengths of 2, 5, 10, 20, and 50 mm and allows for very fast sampling. The probe includes armored duplex cables available up to 200 meters and SMA connectors for easy interfacing with spectrometers.

Applications: Ideal for laboratory settings where large numbers of samples are analyzed routinely, the Big Dipper is also excellent for in-situ analyses, tracking kinetic and evolving reactions.

Specifications:

• Optical: Path length range of 2 to 50 mm, fused silica lens/window material, 0.32 NA, and typical efficiency of 45% at 500 nm.
