TECHSPEC Raman Longpass Edge Filters
POSTED 10/08/2012
High transmission of desired energy and maximum rejection of laser wavelengths
Barrington, N.J.-Edmund Optics (EO), the premier provider of optical components, introduces TECHSPEC® Raman Longpass Edge Filters. These versatile filters are designed to create a sharp transition between transmitted Raman signals and blocked laser wavelengths.
Ideal for Raman Spectroscopy or Life Sciences Instrumentation
TECHSPEC Raman Longpass Edge Filters are an ideal single filter solution for reducing spectral noise in Stokes shift applications. These precision filters offer high transmission to detect weak signals - they can detect even the smallest Raman shifts. TECHSPEC Raman Longpass Edge Filters provide deep blocking for maximum laser rejection. They are an excellent choice for integration into Raman spectroscopy or confocal microscopy systems for both OEM and laboratory use.
Durable hard coated design
The filters' hard coated design offers outstanding transmission characteristics when compared to traditional coated filters for greater durability and cost savings. TECHSPEC Raman Longpass Edge Filters are robust and will stand up to the normal cleaning and handling associated with a high-quality optical component in a wide variety of demanding applications. TECHSPEC Raman Longpass Edge Filters are available in 325nm, 355nm, 473nm, 488nm, 514.5nm, 532nm, 632.8nm, 785nm, 980nm and 1064nm cutoff-wavelengths in both 12.5mm and 25mm diameters. All of these filter sizes and diameters are in stock and available for immediate delivery for fast turnaround and excellent value.
