67-026 25 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 438nm

The 67-026 is a 25 mm diameter Bandpass Filter, specifically designed for fluorescence applications with a central wavelength of 438nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase on their website. The filter's current status is "in stock", making it readily accessible for immediate use.

The filter is made from UVFS MAL-1965 material, a common choice for optical applications due to its excellent properties. It has a circular base shape, a geometry that is often preferred for its uniformity and ease of integration into various systems. The filter's diameter is 25mm, and it has a thickness of 2mm, providing a robust and stable platform for optical interactions.

The 67-026 filter's physical data includes a cut-on wavelength of 424nm and a cut-off wavelength of 452nm. This range is specifically chosen to allow transmission of light around the central wavelength of 438nm, while effectively blocking unwanted wavelengths. The cut-on and cut-off values are critical in determining the filter's performance and are carefully controlled during the manufacturing process.

The filter is coated with EDm 67-012 on both the front and back surfaces. This coating enhances the filter's performance and durability, providing a hard-coated surface that can withstand the rigors of regular use. The filter's shape is thin lens, a design that minimizes optical aberrations and ensures optimal performance.
