Laser Line Filters
High Transmission at Laser Wavelengths: These filters exhibit high transmission efficiency (>90%) at the specified laser emission wavelengths, ensuring minimal loss of laser power.
Out-of-Band Blocking: They provide excellent attenuation outside the narrow passband, effectively suppressing ambient light and background noise.
Steep Slopes: Laser line filters feature steep transition slopes between the passband and the stopband, ensuring precise isolation of laser wavelengths.
Flat Passband Profile: Maintains a flat transmission profile within the designated wavelength range, minimizing wavelength distortion and maintaining signal integrity.
Durable Construction: Engineered with advanced dielectric interference coatings, laser line filters are durable and capable of withstanding the rigors of various optical environments.
Standard and Custom Options: Offers a wide range of central wavelengths (337.1nm to 1550nm) to accommodate various laser types and applications.
Applications: Laser-Based Spectroscopy, Confocal Microscopy, Flow Cytometry, Fluorescence Imaging, etc.
