330FIB25 25 mm Dia. Standard Interference Bandpass Filter 330nm
The 330FIB25 is a 25 mm diameter Standard Interference Bandpass Filter, specifically designed to transmit light in the 330nm range. This filter is sourced from Knight Optical, a reputable vendor known for their high-quality optical components.
The filter is made from UVFS Mal- 1965, a material specifically chosen for its optical properties in the ultraviolet spectrum. It has a base shape of a circle, a common choice for its ease of integration into various optical systems. The filter's thickness is 6.1mm, providing sufficient structural integrity while minimizing unnecessary weight.
The 330FIB25 features a cut-on wavelength of 325nm and a cut-off wavelength of 335nm, ensuring a tight bandpass around the desired 330nm wavelength. This precise wavelength control is crucial in many applications, such as fluorescence microscopy, where specific wavelengths need to be isolated.
The filter's coating is KNI 330DIB, applied to both the front and back surfaces. This coating enhances the filter's performance by reducing surface reflections and improving transmission. The filter's shape is a thin lens, further optimizing its performance in optical systems by minimizing optical aberrations.
