Softing of light

Post by Harald »

Hi gang,

This is my latest project when it comes to softing of light. I have used Lee Filters #400 LeeLux on both sides of the rings.

The rings come from plumbing supplies bought at a local store, nothing fancy. Filters on both sides of the rings. Have heard so many times that people use double filters, but never with spacing between the filters.

I will try it out next week on some micro minerals.

The space between the filters is about 10mm as I think the first filter near the LEDs will soften and the second filter will give a very even light.

Works in my head :roll:

Are you worried about the LEDs heating up the front barrel of the objective? For high NA this could have a significant effect, though I do not have experience with such a system.

Hi Lou Just,

I have used this light source before without problems

Hope not my soft filter will cause any issues

I will try it out later, maybe next week
Kind Regards

If there is any effect, it would depend strongly on the NA of the objective.

Looking forward to seeing results. Putting space between diffuser layers is something I've read about from time to time. I use that detail as well.

I was testing it out today

As I work in a basement, the temperature is relatively low

No heat on the objective at all

Think it worked like a charm

I will post an new image, maybe later tonight if I'm done working on it
Kind Regards
