SIGMAKOKI Low Dispersion Mirror For High Power Femtosecond Laser φ30mm P Polarized Light 775-825nm　FLMHP-30C05-800

Feature

• It is a laser mirror with a small wavelength dispersion which can be used even for ultrashort pulse laser with a pulse width of 100 fs or less.
• Special thin-film designs are optimized to take into account wavelength dispersion, wavelength bands, and laser capacity.
• This reduces the spread of the pulse width caused by reflecting multiple mirrors.
• Three types are available: standard FLM1, FLM2 with a wide wavelength band, and FLMHP with high laser capacity *.
• It can be used for the optical system of a femtosecond time-resolved spectrometer or for the application of a femtosecond laser to a microscope.
• We also have a Surface Accuracy Guarantee Mirror (HTFM) that guarantees surface accuracy after coating.
• Wavelength dispersion may not be compensated if the camera is used at an angle other than 45 degrees.
• * Reflectance wavelength characteristics of dielectric multilayer films vary depending on the polarization state of the incident beam.
• * P-polarized light has a lower reflectivity and a narrower reflection band than S-polarized light.
• * The reflectance of the specification is expressed as the average value of the reflectance of P-polarized light and S-polarized light.
