86-091 25 mm Dia. Hard Coated OD 4.0 10nm Bandpass Filter; t=3.5 mm 1550nm

The 86-091 is a Bandpass Filter, specifically designed for use in optical systems requiring a narrow bandwidth transmission. Sourced from Edmund Optics, this filter has a catalog number of 86-091 and is available for purchase through their website, where it is currently listed as in stock.

This filter has a circular shape, with a diameter of 25 mm and a thickness of 3.5 mm, making it compatible with a wide range of optical systems. The material used in its construction is UVFS Mal- 1965, a choice that contributes to its overall performance and durability.

The 86-091 filter is designed to transmit light within a specific wavelength range, centered around 1550 nm. The cut-on wavelength is 1545 nm, and the cut-off wavelength is 1555 nm, providing a precise 10 nm bandpass. This characteristic makes it ideal for applications that require narrowband filtering, such as laser systems or spectroscopy.

The filter features hard coating on both the front and back surfaces, identified as EDM 86-088. This coating enhances the filter's durability and resistance to environmental factors, ensuring reliable performance over time. The filter's shape is described as a Thin Lens, indicating its potential use in systems where minimal optical path deviation is desired.
