The 67-027 is a Bandpass Filter, specifically designed for Fluorescence applications, available from Edmund Optics. This filter boasts a 25 mm diameter and a thickness of 2 mm, making it a robust and compact solution for various optical setups.
The filter is designed to transmit light within a specific wavelength range, centered at 472 nm, with a bandwidth of 30 nm. This is achieved through the use of a hard coating, denoted as 'edm 67-013' on both the front and back surfaces. This coating ensures high transmission and durability, making the filter suitable for demanding environments.
The physical data of the filter is also noteworthy. The cut-on wavelength is 454.5 nm, and the cut-off wavelength is 489.5 nm. This means that the filter begins to transmit light at 454.5 nm and stops transmitting at 489.5 nm, effectively isolating the desired wavelength range.
The filter is shaped as a Thin Lens, which can be beneficial in certain optical configurations. It is currently in stock and available for purchase through the provided weblink.
