EDMUND OPTICS NEWPORT OMEGA 1" mounted and similar items

Special laser optical filter 410nm bandpass (unknown brand) Description: no longer needed in my lab. I have not full information (only bandpass), but you may know enough of it given this information. Tests done with "mirror side" facing light source. Measures: Mount is exactly 1" 25,4mm (filter a bit smaller to fit in mount). Thickness is 0,246" (6,24mm). Catalog number and other info: D.O. #15-20140 S-DUD 8-4 (this last number might be the cut-on cut-off tolerances in nm) Straight light-through behaviour (0º angle): LED HALOGEN light source show light PURPLE. Edge-on light-through behaviour through HALOGEN light source (around 80º angle): PURPLE color. Weight: 5,8gr. Condition: filter shows some aging in the light-in side mirror side (outter portion only) and some small cleaning marks. No scratches or haze. I would say GOOD-EXCELLENT OVERALL condition. Delivered in original package. Shipping: Remember I combine shipping. Ask for invoice (through) BEFORE paying if I didn't send it to you yet!) TERMS: My descriptions are faithful. If I say an optic is clean, then it is clean. I am NOT a cold Corporation thinking up just in numbers and my selling here is a long term responsability activity. I want you to be sure you are paying for what I am describing. In fact, most of my items are over-described (I tend to look specifically for problems instead of overlooking them). If for some reason you think I missed it up, get back to me. I don't tend to mess around with people. Like most of you, I work out my life with others "Quid Pro Quo" style, which means that I TRY TO DO OTHERS WHAT I WOULD LIKE THEM TO DO WITH ME! :) My cameras and optical stuff are all stored in dry safe containers here (no leaks, no humidity, no vapors). They will be delivered to you exactly as you are watching them here. I accept HAND-ON DELIVERY if you live in Madrid. I accept returns as long as: 1) Items must be received back in same condition as when they left here. 2) You pay return shipping costs (unless there is a mistake or any other issue with your order, in which case I would pay them).
