What are 'Locked-in' eyepieces?

[Jason Green]

Evening all,

Sorry if this is in the wrong place, but I couldn't think of anywhere more relevant!

I've been looking through various websites for stereo-microscopes and keep coming across ones stated as saying they come with 'Locked-in' eyepieces.

What is Locked-in, exactly; does this mean they have a secure catch to prevent them dropping-out and breaking when in transit, or are they unchangeable - ie. part of it?

Thanks for any assistance

Take care,

Jason

Hi Jason

A term used to suggest they are 'student' tamper proof! Unless of course the student has a screwdriver handy

Thanks for the reply John - so a pair of WF20x could be used, with the previous WF10x simply being unscrewed first? Ah!!!

I've seen a beautiful dissecting microscope with a 4x objective and WF10's supplied - 40x. Does this mean I could use any WF20x to get 80x? (there are 'scopes for about £280 that have a 4x objective with WF20x supplied)

Hi Jason

You would have to check with the supplier, but generally the eyepieces can be locked, preventing theft and eliminating the possibility of damage during transit.

Ah, thanks. My Apex Examiner (WF10X, 2x obj.) doesn't have a locking function - they just pop in and out.

Two questions - what exactly is the lock involved, how could it be unscrewed?

Are WF20X eyepieces a universal size, and would they fit all microscopes that come with WF10X recepticles? Thanks again!
