Chroma Technology​​ staff are thrilled to see their optical filters utilized in capturing an exceptional image of the Supernova Remnant G156.2+5.7 (SNR156). This is an extremely faint and rarely imaged celestial object in the constellation Auriga.

This project, led by the​​ Deep Sky Collective, required a collaborative mosaic approach due to SNR156's vast size. Over four months of imaging and an additional two months of meticulous pre- and post-processing resulted in a breathtaking image. This marks the longest ever integration time on this supernova remnant—totaling over 385 hours!

Chroma manufactures the highest quality astronomy filters and astronomy filter sets with durable, sputtered hard coatings using single substrates of the best glass, eliminating the need for laminations.

Drug developers depend on accurate identification and molecular analysis of the components within pharmaceuticals to optimize product quality across solid and liquid formulations. Since a unique Raman spectral fingerprint exists for every molecule, Raman spectroscopy is increasingly the preferred technique to examine the structure and distribution of components within drug formulations.​​ 

Iridian Spectral Technologies offers a range of standard Raman filters and custom solutions, but the possibility always exists that a distinct filter combination will be required for a particular application. Accordingly, Iridian can customize filter design to meet​​ your​​ requirements.

A recently published research paper is entitled, “Cavity-Enhanced Emission and Absorption of Color Centers in a Diamond Membrane with Selectable Strain.”

The experimental setup for this research used a ZET730nf filter from Chroma Technology.

Chroma Technology is a leading manufacturer and OEM supplier of high performance optical filters optical filter sets,​​ and filter accessories, used in a wide range of applications, including health care, biomedical research, remote sensing, machine vision, and aerospace.​​ 

One of the most common questions that customers ask the staff of Chroma Technology is “How should I clean my filters?”

This is an important task for maintaining optimal performance. Incorrect cleaning or handling can risk damaging your filters so it’s critical to do it right.

Chroma has a detailed cleaning guide on the company website.
