Delta Optical Thin Film now offers filters with up to four wavelength pass-bands for multi-spectral fluorescence instrumentation.

The commercial availability of Light Emitting Diodes at almost any wavelength combined with Multi-Bandpass Filters have enabled a new type of Fluorescence instrumentation. These new instruments offer ultrafast switching between different wavelengths with-out the need for moving or replaceable filter parts.

We are proud to present our newest Multi-Bandpass filter products; a quad-band emission filter and a quad-band dichroic beamsplitter.

These products are excellent examples of the kind of filters that Delta Optical Thin Film can design and manufacture for our OEM-customers.
