87-241 25 mm Dia. Hard Coated Dual-Band Fluorescence Bandpass Filter; t=2 mm 512/630nm

The 87-241 is a high-quality Dual-Band Fluorescence Bandpass Filter, sourced from the renowned optical components vendor, Edmund Optics. This filter, with a diameter of 25 mm, is designed to allow transmission of light within specific wavelength ranges, making it ideal for various applications in the fields of imaging, spectroscopy, and laser technology.

The filter is of the Bandpass type, which means it permits the passage of light within a particular range of wavelengths while blocking out light from other regions of the spectrum. This specific model is designed for dual-band transmission, with center wavelengths (CWL) at 512 nm and 630 nm. The CWL is a critical parameter in filter selection, as it determines the specific color or range of the light that the filter will allow to pass through.

The 87-241 filter is made from UVFS Mal-1965, a material known for its optical properties and durability. It has a thickness of 2 mm, providing sufficient structural integrity while minimizing optical distortions. The filter's geometry, including its 25 mm diameter, is designed to fit standard optical systems and components.

The physical data of the filter indicates a cut-on wavelength of 500.5 nm and a cut-off wavelength of 523.5 nm. These values are crucial in determining the filter's performance and its ability to block out unwanted wavelengths. The filter's coating, both on the front and back, is EDM 87-233, which enhances its durability and performance.

In terms of shape, the filter is designed as a Thin Lens, which is often used in optical systems to focus light. This shape further expands the filter's potential applications, making it a versatile component in various optical setups.

The filter's status is "Valid - in stock" as per the vendor's website, indicating its availability for immediate use. For more information and potential applications, users can refer to the vendor's website through the provided weblink.
