Inside a maxys

[300EVIL]

someone posted a couple years ago in reference to what the heatsink came from

They look like high current resistor heatsinks.

guys, there is no magic in the driver, its the optics and quite possibly that diode is a little better quality then most. Its a sony,although a industrial product, not a DVD one. Since Chuck was a video guy, he had connections at sony 's industrial and OEm, also known as Sony Professional. I just don't know which part number. I dont want to tear mine down, but if the optics were to appear here, I'd run them on the optical bench and figgure out what was what. There is a bit more to it then just focal lengths. My gripe is that driver board is not big enough to have enough diode protection on it. In its time it was a good product, well placed in the market and many of us needed them when it came out.

The lens tube/optics are straight from Alltronics

Yeah, I just want to run analog modulation. Since I see theirs no magic or fancy drivers to them I'd really like to gut it and change the driver.
Thanks!

They look like high current resistor heatsinks.

Now that you mention that, the more like resistor heatsinks they look!

I'll have to have a look around for them, they look good for red modules

Infact ....



Same kinda thing!

The guys at LASERPOINTERforums use these resistors as heatsinks in their projects.

They burn them out with highcurrent...and pull out the resistorwire and epoxy after that.

me being a cheapskate only used one resitor housing and cut it in two

rob do you have a link to those?

or anyone else have a link to a good sized resistor heat sink??

I just ordered up some 50 W & 100 W resistors from my local electronics wholesaler
I didnt use the 100s still got them here - I just selected a value that wa sin stock and was the cheapest

Thats not a resistor heatsink its a RF dummy load from Diamond. well, 50 ohm non inductive special resistor designed for no back reflections at RF. Probably considerably easier to remove then a wirewound.

Yep, RF dummy load.
