589DIN25 25 mm Dia. Narrowband Interference Bandpass Filter 589.6nm
The 589DIN25 is a 25 mm diameter narrowband interference bandpass filter, specifically designed to isolate the 589.6nm wavelength. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is of the bandpass type, which means it allows a specific range of wavelengths to pass through while blocking out others. In this case, the passband ranges from 588.1nm to 591.1nm, with the central wavelength at 589.6nm. This makes it ideal for applications that require precise wavelength selection, such as fluorescence microscopy, spectroscopy, and laser technology.
The 589DIN25 is made from UVFS MAL-1965, a material known for its excellent optical properties. It has a circular base shape and a thin lens shape, with a thickness of 6.1mm. This combination of material and shape ensures high transmittance and low autofluorescence, which are crucial for sensitive optical measurements.
The filter's front and back surfaces are coated with KNI 589DIN, a proprietary coating developed by Knight Optical. This coating enhances the filter's performance by reducing reflection and increasing transmission. It also provides excellent environmental stability, ensuring the filter maintains its performance characteristics even under harsh conditions.
The 589DIN25 is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website provided in the item data.
