1. some are of the opinion that I am not 'normal', so my viewpoint may not be valid; but both of my dogs will attest that I am not 'crazy' (the cat will not comment), and I do not consider you concerns to be 'crazy'.
2. look at ophiropt.com - NOT a personal endorsement, but a colleague has used their instruments with no complaints. 3. CFR 21, Sec I, subch J; and IEC60825 - may or may not be applicable depending on function and 'class'. Also, CE magazine has run some laser safety articles. luck, Brian From: [email protected] [mailto:[email protected]]On Behalf Of Kunde, Brian Sent: Tuesday, October 14, 2008 8:20 AM To: [email protected] Subject: Light Meter Recommondations First, I want to apologize to those who might be offended by this email and my lack of knowledge on this topic. But from time to time we hear about law suits (possible frivolous) dealing with eye damage from devices with displays and LEDs. What we would like to come up with a simple method to pre-test products with some kind of light meter and have it give us a number or graph that we can quickly determine if there is any reason to be concerned. So, 1. Am I crazy for even thinking this way? 2. Can anyone recommend such a light meter or other measuring device (make/models)? 3. Can anyone give me rough numbers, values, or a standard which defines light levels/frequency that we can use as a go/no-go value? Thanks to all for your time.
