Attenuator set

The trigger option is effective for low repetition frequencies (below the frame rate).
Mainly for measuring pulsed light. It is used to synchronize laser and camera exposures, especially when measuring low repetitive pulses below 10 Hz.
The pulsed laser (10Hz) will not be visible unless the camera is synchronized at 30Hz.
The trigger option is not required if the repetition frequency is about 100Hz or higher, such as when measuring pulses. The trigger option is recommended for low repetitions such as 10Hz.

ND filter set (NDFS-CA50)

In order to measure a high-intensity laser beam, an ND filter set (NDFS-CA50) that can be dimmed and its mount are required.

* If the laser beam power becomes stronger than 100 mW, the absorption lens ND filter (NDFS-CA50) will generate a thermal lens effect, so a beam splitter that can further reduce the light is required.

Lead time: Contact us

LaseView camera set series LaseView-CA50-NCG compatible
Wavelength range: 350-700 nm or 650-1100 nm
Power：< 1 W（For vertically polarized light） < 10 W（For horizontally polarized light）
ND filter (NDFS-CA50)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 (NDFS-CA50) 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 (NDFS-CA50) 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.

3. Micro-beam measurement set

In order to measure beams smaller than 30 μm, a set of microbeam measurement optics is required. As a set of microbeam measurement optics, we have achieved “”high magnification, high NA, and ultra-low aberration”” that is not available anywhere else.
