Dimensions: 100 x 200mm

These two bullets summarise the rules for combining light heads and filters.

  • For any excitation light head, you can pair it with any of the barrier filters that are normally used with a light head of a longer wavelength.
  • For any barrier filter, you can pair it with any of the light heads that are normally used with a barrier filter of a shorter wavelength.

Standard light source/filter combinations:

Designation Excitation Emission
UV – Ultraviolet 360 – 380nm 415nm longpass
VI – Violet 400 – 415nm 450nm longpass
RB – Royal Blue 440 – 460nm 500nm longpass
RB – Royal Blue 440 – 460nm 500 – 560nm bandpass
