67-842 25 mm Dia. Mounted Traditional Coated Bandpass Interference Filter; t=5.9mm 750nm

The 67-842 is a 25 mm diameter mounted bandpass interference filter, designed and manufactured by Edmund Optics. This filter is specifically engineered for applications that demand high-quality optical performance and precise wavelength selection. The filter features a center wavelength of 750 nm, with a full width at half maximum (FWHM) of 10 nm, providing a narrow and specific passband.

The filter is constructed with a base shape of a circle, ensuring uniform illumination and ease of integration into various optical systems. It boasts a thickness of 5.9 mm, providing sufficient mechanical stability while maintaining minimal optical path differences. The filter is coated on both the front and back surfaces with EDM 67-775, a proprietary coating developed by Edmund Optics, enhancing its overall transmission and durability.

The 67-842 filter is designed with a cut-on wavelength of 745 nm and a cut-off wavelength of 755 nm. This ensures a sharp roll-off on either side of the passband, minimizing unwanted out-of-band transmission. The filter's geometry and physical data make it an ideal choice for applications such as fluorescence microscopy, spectroscopy, and other precision optical measurements.

In terms of shape, the 67-842 filter is designed in a thin lens format, allowing for easy integration into various optical systems.
