Et700-75M C 25 mm Dia. Sputter Hard Coated; Bandpass Filter

The Et700-75M is a Bandpass Filter, specifically designed and manufactured by Chroma, a renowned vendor in the optical industry. This filter, with a circular base shape, is characterized by its 25 mm diameter and 1 mm thickness, making it a compact yet highly effective component in various optical systems.

The filter's primary function is to allow light within a specific wavelength range to pass through while blocking out light from other wavelengths. The Et700-75M is designed to pass light with a central wavelength (CWL) of 700 nm, making it ideal for applications where this specific wavelength needs to be isolated or emphasized.

The filter's physical data includes a cut-on wavelength of 662.5 nm and a cut-off wavelength of 737.5 nm. This means that it begins to transmit light at 662.5 nm and stops transmitting at 737.5 nm, effectively filtering out light outside this range.

The Et700-75M features a Sputter Hard Coating on both the front and back surfaces. This coating enhances the filter's durability and resistance to wear and tear, ensuring its longevity and reliability in various operational conditions.

The filter's shape is classified as a Thin Lens, indicating its potential use in applications where light focusing or collimation is required. This versatile filter is available for purchase directly from Chroma's website, where it is currently listed as in stock.
