Re: Looking for complete BH2 "UCD" DIC set

Hi all, I'm still looking for this set of items. 🙂 My eBay feedback can be found here: https://www.ebay.com/usr/mxlh5995 We can do the transaction through eBay or a trusted middleman if you prefer those options. By the way, Macro_Cosmos informed me that actually the BX DIC condenser doesn't fit BH-2...

Re: Cleanest microscope slides for D/F microscopy

I only use 1.5H coverslips, which are too expensive for me to use as disposables on good conscience. So I do coverslip cleaning once a week. I use a Magnasonic brand ultrasonic cleaner I picked up off eBay used for $15. 30 parts distilled water, heated - 1 part Dawn dish detergent usually takes ever...

Re: Olympus BH-2 (BHS) LED Conversion

Retrodiode and similar consumer-market replacements for microscope lamps are bad IMO for two reasons: 1) The CRI and tint is horrific. I saw a "high-end" one using an XHP70, which is a green tinted mess of an LED. 2) Some of them use fans (moving, vibrational parts attached to your microscope...) I ...

Re: High CRI daylight COB recommendations

I recently built a light board of very high CRI COBs. The best parts I found were Bridgelux Thrive - https://media.digikey.com/pdf/Data%20Sheets/Bridgelux%20PDFs/V6_HD_Thrive_Array_RevA_Preliminary_Jun2020.pdf and Sunlike SAWS. The Bridgelux have the highest CRI/Ra I've found in a COB. Their R9 (the...

Re: Monochromatic Microscopes?

There are also economical, extremely good 5x and 10x monochromatic "objectives" with high NA (greater than 0.35 in many cases), zero distortion, perfectly flat fields, and enormous image circles. These are among the best optics in existence, as long as you use the right wavelength of light. They ar...

Re: Monochromatic Microscopes?

Hm, but I mean a microscope where all of the corrective elements are designed for monochromatic light (allowing much better field size & flatness at a given level of manufacturing effort.) I guess on an infinity-corrected microscope, only the objectives would need to be monochromatic, since correcti...

Monochromatic Microscopes?

After reading about monochromatic photomicrography and its benefits, I wondered why there don't seem to be any microscopes designed from the ground up for monochromatic usage? If you only have to make a flat field for one single wavelength, and you don't need to worry about chromatic aberration at a...
