i tried to get technical data on the Ikea USB Lamps, but could not not. Thank you for the German source. No mention of CRI though. But, I have more difficulty with CRI of the LED lamps (see below). There seems to be some difference of opinion on CRI vs NIST developed CQS. ? https://photography.tutsp...

Ray, XY stage marketed by Amscope http://www.amscope.com/catalogsearch/result/?q=xy+stageBy the way, can you give info on the XY stage you are using?
One more benefit of mounting LED source on the stage is that the subject illumination / angle remains constant.
Best,

Boom Stand Horizontal Support Bar Standard Diameter?
This may not be what you are looking for, but flat / square metal stock will be more stable and supports much heavier equipment. See the modified old Nikon Multiphot center dove-tail column for horizontal high-magnification setup. http://www.photomacrography.net/forum/userpix/1511_NikonMultiphot_Hor...

Naturally I have been following this thread and it is nice to see there are others out there making the most of bracketing/stacking. I am well and truly hooked on both options and kick myself when I forget to to take advantage. ... Very much interested on the ongoing discussion - I have one questio...

Pau Some high grade research microscopes, mainly confocal, do this automatically by means of computer controlled piezoelectric focusers placed between objective and nosepiece or at the nosepiece construction itself.

Thank you g4ab, Rik and Pau for the previous postings; Agree, appear to be more suited for low magnification work. VFL manufacturer site lists more applications e.g. machine vision, Laser processing in 3 dimensions(3D printing?) and low power microscopy. One application intrigued me the most was VFL...
