4 March 2016
Our laser leak tester is upgraded.
Now it can be used both for pulse lasers and continuous (CW) lasers.
In case of pulse lasers, non modulated emission
at >= 1kHz of pulse repetition frequency is supported.
We are sure that the laser leak tester is of great help to verify
that emission from laser products is class 1.

13 October 2015 (added later)
Mita Giken has developed a laser leak tester.
This tool is used to verify that accessible emission (laser leak from protective housing)
from laser products is within class 1 accessible emission limit (AEL).
Both class 1 AEL calculation and measurement optics are based on JIS C 6802 : 2014.
Continuous (CW) lasers with wavelength of 400 nm ~ 1100 nm
and emission duration of >=0.4 s is supported.
Japanese version is available now, English version is under consideration.

100~120 V input range "AC adapter" option of biased PIN photodiodes
with 90~132V conventional specification could be delivered to customers without notice.
 If you purchased this option in or after December 2014 and use it at 90~less 100 V
or over 120~132V, please check the input voltage indication on the AC adopter.
In case the indication is "100~120 V", please remove the AC adapter
form the line voltage and contact us. We will try to find the solution with you.
The specification was changed today, as 100~120V input range.
We will send email with upper content to customers
who purchased the option in or after December 2014.
