Delta Optical Thin Film launches several LED and laser bandpass filters. They are optimized for specific LED and laser wavelengths and combine exceptionally large angular tolerance with high transmission and provide at least OD4 out-of-band rejection in a large wavelength range. This makes these filters well suited for machine vision applications with near-infrared LED illumination or Nd:YAG laser […]

…Martin H. Skjelvareid!Last month we invited you to send us your suggestions for a new name for our linear variable bandpass filters for Hyperspectral Imaging. The response was overwhelming, and many of you had brilliant and creative ideas. The name we chose is Bifrost. It was suggested by Martin from Norway. Rainbow filter was the most numerous […]

With Christmas just a couple of days away everybody is preparing for a well-deserved Christmas’ and New Year’s break. At DELTA we have been extraordinarily busy the last few weeks and as a result we have some exciting news to share with you. The optical filter business of DELTA will start in a new set-up […]

We have prepared a short presentation for you that clarifies the notion of optical density (OD) and puts it into context with signal to noise ratio (SNR). In our daily work as filter manufacturer we often talk to customers with an electrical engineering or imaging background. In these and other fields SNR is an important […]
