Hey erns...
* * yes... a ND2 filter will allow you to read a 532nm 200mW laser.

You will need to find your "ND2 Filter Multiplication factor" by using a 532nm
under 100mW laser..

1) shine the <100mW laser on the optical sensor without the ND filter and
* * take a reading.
2) shine the <100mW laser on the optical sensor with the ND filter and
* * take a reading.
3) divide the 1st reading by the 2nd reading to get your "ND2 Filter Multiplication
* * factor" for 532nm.
4) Multiply any 532nm readings by that factor when using your ND2 Filter.

Remember that your 532nm power reading may contain IR power.. 8-)

Hey jerry,

I know you said that they're not accurate for bluray, but is it that the correction factor is too great, or that the sensor itself doesn't reliably detect 405nm light?

Say, I had a few PHRs and wanted to find the strongest (or the one with the highest mW/mA gradient) and set them all to exactly 50mA, would this sensor be able to identify the most powerful one at that power input? Something our eyes can't do because of wavelength variations.

Thanks, aXit.

Hey aXit...

The 120mW LPM Module's Sensor is not capable of reliably detecting
the 405nm wavelength since it is outside of its Spectral Response..

We are working on a New 150mW LPM Sensor Module with a New Optical
Sensor that may be able to reliably detect the 405nm wavelengths..

As soon as all the test results are in... they may be an the market before
Xmas...

Pre-order?

Sounds good though, I guess I shouldn't press for price...
