Et460-30X C 25 mm Dia. Bandpass Filter by Chroma
The Et460-30X is a Bandpass Filter with a circular base shape, designed and manufactured by Chroma. This filter is specifically engineered to allow light in a narrow range of wavelengths to pass through while blocking out other wavelengths. The central wavelength (CWL) of this filter is 460 nm, making it ideal for applications that require the precise transmission of light in this range.
The filter has a diameter of 25 mm and a thickness of 1 mm, providing a balance between compactness and durability. The cut-on wavelength is 445 nm, and the cut-off wavelength is 475 nm, further enhancing its ability to filter specific wavelengths. The coating on both the front and back surfaces of the filter is 'chr et460 30x 5715', which contributes to its high performance.
The Et460-30X is available directly from Chroma's website, and the link provided in the item data indicates that it is currently in stock. This filter is part of the UVFS MAL-1965 material ID family, suggesting that it shares certain properties with other filters in this series. The filter's shape is described as 'Thin Lens', implying that it is designed to minimize optical aberrations and distortions.
