Thank you for your interest and inquiries.

4 March 2016
Our laser leakage tester has been upgraded.
The instrument now supports both pulsed lasers and continuous-wave (CW) lasers.
For pulsed lasers, non-modulated emissions
with pulse repetition frequencies of 1 kHz or higher are supported.
This laser leakage tester is highly effective for verifying
that emissions from laser products comply with Class 1 Accessible Emission Limits (AEL).

13 October 2015
Mita Giken has developed a laser leakage tester.
This instrument is designed to verify that accessible emissions
(laser leakage from protective housings) from laser products
remain within the Class 1 Accessible Emission Limits (AEL).
Both the Class 1 AEL calculations and the measurement optics
are compliant with IEC 60825-1 : 2014 (JIS C 6802:2014).
The system supports continuous-wave (CW) lasers with wavelengths
from 400 nm to 1100 nm and emission durations of 0.4 seconds or longer.
The Japanese-language version is currently available.
