It's really old. I've seen ads from like the 60s with this model in it. Surprised it still works, but hey!

Oh. Bloom, there isn't a PCM on this one =p Just another slit. I was thinking about adding a PCM though. I don't think all monochromators are designed that way. At least not this one!

The PCM? What's that stand for? Because I opened up the monochromator and it's literally just a grating and a few mirrors.

Updated with pictures and errthang! Enjoy!

Re: Got a Monochromator! So before I headed out to class, I did some rudimentary testing, and it looks like it's well calibrated (tested it on a 589nm DPSS and my argon on stand-by). It just reads 2nm high, it looks like. Gonna open it up this weekend, possibly.

How wrong can you be? This is what shows that you're still new around here. Power is NOT everything. If it's above ~100uW, it's visible, so it's still a viable laser for this hobby. I take it you're not interested in the 609nm lasers that may be coming out soon because they are "too low...

Hey everyone. So a few days ago I decided to take a risk and bid on a Bosch and Lomb monochromator. Anyway, long story short, I won it for about $230 and it arrived today! Without further ado, here are the pictures that I know you guys have been waiting for! The Monochromator! Now, that's...

I'm glad you won, jimmy. I really wish I had the chance to make my phaser, but you're design is so innovative, so fresh, and so unique, that the forums needs to see it. Great work. +however many I give.

This is very true. Why do we often see that analog control is "better" than TTL though? Just curious. Because TTL is essentially PWM, is it not?

I was lurking right when the 445s came about, so they were still quite astonishing. I can't say I am the oldest member here, unfortunately, so I don't have as many great stories. But I remember always being jealous of RHD because he and I joined very near each other, temporally, and he always...

Well, it would all depend on the pricing the machinist would want to set for the host. I am sure I could do some sort of driver like that for <$25 pretty easily.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please It has an adjustable entrance slit, methinks. There's a dial around the slit that is set at ~5mm in the pictures, but it goes down to <0.5mm.

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Bausch Lomb High Intensity Monochromator Cat 33 86 76 | eBay Bidding on it. Please no one else :D

Actually, I was reading through old threads of mine, and that was an idea I had a LONNNGGG time ago. But I figured that not many people would be particularly interested since most hosts wouldn't accommodate that. Maybe I can work with one of the machinists around here and see if we can get a...

That's the one part I will have to keep a trade secret =p Usually I wouldn't except it's very similar to a part I use for the BlitzLinear, and that I do want to keep secret.

This is why I love this community.

Hah. Probably =p Well, contest is over. But doesn't mean this won't get put to good use. Just need to get the funds then to get one of them diodes.

Damn :( I swear I was tied for second :\

Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please Alright. Will do. I'll shoot him an email after work.

Okay, yes, it may not be for something good. But, on the other hand, we don't know what he's up to. I know I've asked some pretty sketchy questions but they were about experiments, NOT breaking and entering. You guys make a lot of assumptions for this sort of thing. If someone breaks a window...
