Last month Delta Optical Thin Film  have invited their clients to send them their suggestions for a new name for their linear variable bandpass filters for Hyperspectral Imaging. The response was overwhelming, and many of their clients had brilliant and creative ideas. The name Delta chose is Bifrost. It was suggested by Martin Skjelvareid from Norway.

Rainbow filter was the most numerous and logical suggestion. Mantis filter, named after the famous mantis shrimp, was a hot candidate too. While we like all of them, they chose Bifrost because it takes the idea of the rainbow filter one step further, and because as a term from norse mythology it connects to the home country of Delta Optical Thin Film A/S Danmark – this is also the reason why they chose the Danish spelling Bifrost.

Bifrost is a burning rainbow bridge that reaches between Midgard, the world of man, and Asgard, the realm of the gods. The bridge ends in heaven at Himinbjörg, the residence of the god Heimdallr, who guards it from the jötnar (frost giants).

Bifrost as rainbow bridge not only reminds of the visual appearance of their filters when looked through at sunlight. It also symbolises that their filters are an enabling key component in tomorrow's Hyperspectral Imaging cameras  – a bridge between so far unmet user requirements and new applications of Hyperspectral Imaging.

BTW, Martin is planning to have his price, one of their Bifrost filters, mounted in a camera so he can get started with advanced Hyperspectral Imaging.

Delta Optical Thin Film is closed for summer holiday from July 11. On July 25 their staff looks forward to discussing your filter requirements with you again following their motto High-performance filters for demanding OEM customers.
