Athenesta set

ND filter set

In order to measure a high-intensity laser beam, an ND filter set that can be dimmed and its mount are required.

Price: US$ 760 (excluding tax)
Lead time: about 1 week
* If the laser beam power becomes stronger than 100 mW, the absorption lens ND filter will generate a thermal lens effect, so a beam splitter that can further reduce the light is required.
  • Absorption ND filter
  • OD=0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 1.0, 2.0, 3.0, 4.0
  • 1 inch
  • With ND filter diagonal mount

Attenuating optics set with beam splitter

Fig: Attenuating optics set with beam splitter

Model number: OAS-CA50
Price: US$ 1480 (excluding tax)
Lead time: about 2 weeks
  • LaseView camera set series LaseView-CA50-NCG compatible
  • Wavelength range: 650 – 1050 nm
  • Power:< 1 W(For vertically polarized light) < 10 W(For horizontally polarized light)
  • ND filter included:OD=2.0, 3.0, 4.0, 5.0

* Can be attached directly to the camera.
* The attenuation factor of the beam splitter varies depending on the polarization direction. (P-polarized 0.9%, S-polarized 9%)
* Although the ND filter has an AR coating, interference fringes may occur if the coherence of the laser beam is high.
* An appropriate attenuation rate is not guaranteed under the specified incident light conditions.
Add or replace an ND filter with an appropriate attenuation factor according to the conditions.
* There are the following restrictions on beam polarization.
・ Horizontal or vertical linear polarization
・ Uniform polarization characteristics throughout the beam
・ If these conditions are not met, the correct intensity distribution may not be measured due to the polarization dependence of the beam splitter.
* Posts for height adjustment and fixing are not included.
