Question ID: 512573
I am looking for a dichroic type UV blocking optical filter. It must
meet the following criteria:

transmission from 360nm to 370nm must be less than 1%
transmission at 400nm must be greater than 40%
transmission from 410nm to 500nm must be greater than 85%

it must be available for immediate purchase and delivery to California
within 2 weeks of purchase
the minimum order must be less than $100
it must cost less than $65 (not including tax or shipping) for a
single filter not smaller than 23mm in length or width
it must be less than 7mm thick (thickness is the dimension along the
axis light is intended to pass through)

a transmission curve for the filter must be availble which shows its
transmission characteristics at the above wavelengths

colored glass like Schott GG400 is not acceptable because it will
fluoresce when exposed to 365nm radiation

dielectric or interference filters will not work because they are angle sensitive

it really needs to be dichroic

this question basically has two parts, one is finding the filter, the
other is finding someone who sells it
and has it in stock and ready to deliver
