BK7A Ø38.1 to 50.8mm

產品名稱 : BK7A Ø38.1 to 50.8mm
產品說明 :
● High reflectance at two separate wavelengths
● Reflect fundamental and harmonic
● Reflect fundamental and alignment beam for UV or Dye lasers

These are useful extra-cavity mirrors which have a high reflectance at both the Nd: YAG/YLF fundamental wavelength and also a wavelength in the visible spectrum. They can be supplied to reflect the laser harmonic wavelength. Alternatively, they can be supplied to reflect a HeNe laser or diode laser alignment beam. For UV applications, because UV beam is invisible to the eye, it is desirable to use a co-linear alignment (He Ne) laser.
