LP02-488RE-25 25 mm Dia. 488nm RazorEdgeUltrasteep Long-Pass Edge Filter by Semrock
The LP02-488RE-25 is a Longpass Filter from Semrock, designed with a 25 mm diameter and a thickness of 2 mm. This filter is specifically engineered for use in optical systems that require precise wavelength management, particularly those operating around the 488 nm range.
The filter's primary function is to allow the transmission of wavelengths greater than 488 nm while blocking those below this value. This is achieved through the application of a specialized coating, denoted as 'sem lp02-488re' on both the front and back surfaces. This coating ensures a sharp cut-on at 488 nm, providing excellent contrast and signal clarity in the desired wavelength range.
The LP02-488RE-25 is manufactured from UVFS Mal-1965, a material known for its optical quality and durability. The filter's thin lens shape further enhances its performance by minimizing optical aberrations and ensuring uniform transmission across the entire aperture.
According to the provided data, this filter is currently in stock and can be purchased directly from the Semrock website. The catalog number LP02-488RE-25 is used for reference, and the filter's dimensions make it suitable for a wide range of optical applications.
