33-321 25 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 386nm

The 33-321 is a 25 mm diameter Bandpass Filter, specifically designed for fluorescence applications with a center wavelength of 386nm. This filter is sourced from the reputable vendor, Edmund Optics, and is available for purchase on their official website. The filter's catalog number is 33-321, and it boasts a 2mm thickness, making it a robust and durable choice for various optical setups.

The filter's primary function is to allow light within a specific wavelength range to pass through while blocking out other wavelengths. In this case, the 33-321 filter features a cut-on wavelength of 374.5nm and a cut-off wavelength of 397.5nm, resulting in a 23nm bandwidth. This precise wavelength range ensures optimal performance in fluorescence applications, particularly those utilizing the 386nm wavelength.

The 33-321 filter is coated with the EDM 33-320 coating on both the front and back surfaces, enhancing its durability and overall optical performance. This hard coating provides an additional layer of protection against environmental factors, ensuring the filter maintains its specified optical properties over time.

The filter's circular geometry, with a diameter of 25mm, makes it compatible with a wide range of optical systems and components. Its thin lens shape further adds to its versatility, allowing for easy integration into existing setups or the design of new ones.
