Default Opinions on these LD's

What do you think about these two options??

individual LD's
650 nm
200 mW power
200 Ma operating current
2.5v operating power
TO18 package (Same as typical diode)

and this module type

Laser Module Specifications:
Beam Shape: Circle
Lens: Glass with AR coating
Wavelength: 658nm
Power: 200mW
Operation Current: 350mA
Driver: Optional, 5V input for driver inside
Dimension: Dia.26x100mm

Please let me know your opinions about these, I have a few on order from the manufacturer to test.

Ken

Are those specs for pulsed? Were there max ratings? And what kind of price are they?

200 mW @ 200 mA seems too good to be true. 200 mW at 350 mA is more realistic and similar to the GB diodes from SenKat. What's the price ?
Keep us informed.

Default Re: Opinions on these LD's

I spoke with the sales guy and he cant check on the specs for the LD until after the Chinese New Year celebrations but I am assuming that it is 200mW from 350 mA input as the module is.

He confirmed the the specs on the module as correct with 200mW from 350mW (continuous not pulsed) as being max operating specs. Price seems a bit high but for a LD, driver, module with collimator and a/r coated glass lens maybe it isnt too bad at $40. *Supposedly a discount is available with larger order.

The dimensions are a little big as well at 20mm x 100mm but I'm not sure how much of that 20mm diameter is built in heat sink and if the end of the tube is cuttable to a shorter length. *The nice thing is all you need to do is hook up a battery needs is a battery with around 5V-6V input (he couldn't check the exact range till after the New Year party but figured 5-7V).

I think I will order a couple to check them out anyway and if they test ok, maybe they wil be an option for people.

Opinions????
