RapidBand stock programme

Share this on social media:

Omega Optical, a Laser Components partner, has launched a new RapidBand stock programme, providing fast delivery for hundreds of bandpass filter combinations in a standard 25mm diameter ring that is just 3.5mm thick.

RapidBand filters are constructed by combining longpass and shortpass edges produced at 10nm increments from 400nm to 700nm. These are assembled in a unique, proprietary air-spaced ring designed to meet the size and quality requirements for many optical systems, and are ideal for applications from fluorescence microscopy to rapid prototyping. Longpass and shortpass edge filters can also be ordered as RapidEdge filters, and are mounted in the same 25mm ring.

RapidBand filters are manufactured with durable dual magnetron sputtered coatings, and will have 85 per cent typical transmission, OD5 average and OD4 minimum blocking from UV-1100nm for silicon detectors, a minimum 20.9mm clear aperture, and ¼ λ TWD @ 633nm. Theoretical spectral curves of the finished bandpass filters are available, calculated from measured edge filter spectra.

More than 350 possible RapidBand combinations and more than 50 longpass and shortpass RapidEdge filters are currently available, with additional edge filters and bandpass combinations planned for when the programme’s inventory is expanded.
