50% off at Edmund Optics
If you’re like most people, you can get the vast majority of your holiday shopping done at Edmund Optics. They’re having a Cyber Monday sale this Monday, November 26th. Use code Cyber12 at checkout.
Here’s the deal, they’re offering 50% off of these product families: Clearance, Recertified, Anchor
The first two categories are self explanatory, but the third is an interesting product group so it’s worth a post to highlight it.
The anchor products (optics, mostly) come in different grades.
Commercial grade = meets stated spec
Experimental grade = up to 10% off stated spec
Grade 1: Normal, high quality product. Edged.
Grade 2: Chipped, stained, or otherwise slightly messed up. Not edged.
They’re already pretty cheap, so you can pick up a lot of optical elements for not much cash all in one go (e.g., protected gold 1″ diameter mirrors, $17.50 at Edmund’s Anchor section (and just $8.75 after the 50% discount), or $55.00 at Thorlabs). They’re not the highest spec stuff, but they’re not bad, and often the performance will be limited elsewhere in the system anyways. Grab some cheap items and mock something new up.
thanks for the heads up. have you used the led ring shown in the picture for intrinsic imaging? I guess this is the one from Advanced Illumination available through Edmund? Do you recommend it – is it stable? How is it mounted in the picture? thanks for you help!
I haven’t. For intrinsic imaging, I use a Volpi low-noise light source and two light probes. I’ll probably transition to LEDs, but haven’t yet. My worry with a ring light is that it doesn’t offer flexible positioning, which is key for getting uniform illumination.
