84-089 12.5 mm Dia. Hard Coated Fluorescence Bandpass Filter; t=2 mm 769nm

The 84-089 is a Bandpass Filter, specifically designed for Fluorescence applications, available from Edmund Optics. This filter boasts a 12.5 mm diameter and a thickness of 2 mm, making it a versatile and robust option for various optical setups.

The filter is designed to transmit light within a specific wavelength range, with a Center Wavelength (CWL) of 769nm. This means it allows light around this wavelength to pass through while blocking other wavelengths. The filter's Cut-On wavelength is 745nm, and the Cut-Off wavelength is 793nm, further defining its transmission characteristics.

The 84-089 filter features hard coating on both the front and back surfaces, denoted as 'edm 84-089'. This coating enhances the filter's durability and resistance to wear and tear, making it suitable for demanding environments.

The filter's geometry is defined by its circular shape and thin lens design, which contributes to its ease of integration into various optical systems. The catalog number for this item is 84-089, and it can be found on the Edmund Optics website, where it is currently in stock.
