StellarNet offers a low-cost, rugged, SATR (Sapphire Attenuated Total Reflection) probe that is ideal for use in an industrial process environment.
Extreme Temperatures & Pressures – It is capable of operating at temperatures from -50°C to 300°C and at pressures up to 1200 psi. This outstanding performance is achieved by using Kalrez® O-ring seals.
Micron Pathlength for Concentrated Samples – The sapphire ATR probe is a three-bounce design, which affords a total path length of approximately 1.5 microns. This attenuated total reflection probe is specifically designed for measuring highly absorbent samples. The probe can be inserted directly into the sample for spectral measurements without sample dilution such as analysis of pure inks, dyes and crude oil samples
UV-VIS-NIR Wavelength- Sapphire allows response down to 220nm in samples with an index of refraction up to 1.5, as well as offering excellent resistance to chemical attack.
Rugged for your Process – The optical fiber is 400-micron core fused silica and is clad in stainless steel armor. If needed, the armor can be sealed with Teflon® to provide a barrier to the environment. A four-inch extension tube is added to the rear of the probe to allow direct insertion into a process stream. The extension tube can be adapted to the customer’s process connection requirements.

Diverse medical technologies: How Compact Spectrometers are being used to develop health-related methods and devices
Earlier, I wrote a piece about how StellarNet customers are using compact spectrometers to tackle the multi-headed beast that is cancer. While cancer is a large problem, it is but one of many in the healthcare industry. Diseases need to be understood, treatments need...read more
