35-887 50 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 270nm

The 35-887 is a Bandpass Filter with a diameter of 50 mm, sourced from the reputable vendor Edmund Optics. This filter is designed to transmit light within a specific range of wavelengths, while blocking other wavelengths, making it ideal for applications requiring narrow-band light transmission.

The filter's central wavelength (CWL) is 270nm, which is the wavelength at which the filter's transmission is at its maximum. The cut-on wavelength is 265nm, and the cut-off wavelength is 275nm. This means that the filter begins to transmit light at 265nm and stops transmitting at 275nm, effectively passing light in the 270nm range.

The filter is made from UVFS Mal-1965 material, and it has a thickness of 3.5 mm. The front and back of the filter are coated with EDm 35-873, which enhances its performance and durability. The filter's shape is that of a thin lens, making it suitable for use in various optical systems.

According to the vendor's information, the filter is in stock and available for immediate purchase. The item's catalog number is 35-887, and it can be found on the Edmund Optics website for further details and specifications.
