variable oblique filter
variable oblique filter
a simple to make variable oblique filter.it's no idea from myself but I found it a handy tool to share.
this slider comes at the location of the blue filter and can be shifted left and right to ajust the depht.it's made of a piece of a plasic cake box(it's the time of the year ) and some ductape,this can be any color.dimensions 30mm*x150mm.
*depending on your blue filter

Re: variable oblique filter
That is a very nice effect
Roughly where in the system does this get placed? [Seems a stupid question, but I am not familiar with these microscopes]
I have looked in the Bresser manual but it doesnt really show or seem to mention the blue filter's position.

Re: variable oblique filter
I hope this helps(I also didn't find it in the manual but had to find out myself)

Legion air,
I took your idea a bit further. I realized that this can be expanded to produce the dic effect mentioned in the below link.

Here is the normal oblique slider.

Here is 2 slider used to create below videos. The sliders are stacked together to create a blue oblique light on one side and white light from edge on the other side.

Yesterday I tried a combInation of a (variable) darkfield filter and one of my flashlight filters that I placed directly over the lightsource.
Re: variable oblique filter
Looks nice. Combine them together or alone in oblique manner produces nice effect. I have multi color films as well and playing with it . They produce nice image up to 20x. 40x is not good in my experiments.
