EQUAL-THICKNESS DENSITY SETS

These sets of filters are identical thickness for each density value yet also made from absorptive glass.
They find benefit over standard density filters, for example, if used in a convergent beam there is no need to refocus when changing filters.
We offer a set of 5 equal-thickness filters with nominal optical densities – actual densities will be provided with order.
The filters are available from stock in 1" diameter, or custom sizes are available with reasonable leadtimes.


VISIBLE 1” diameter     VISNDSET      one of each: OD 0.1, 0.3, 0.6, 1.0, 1.4 $355


UV 355nm 1” diameter     UVNDSET    one of each: OD 0.3, 0.6, 1.3, 2.5, 3.6 $445


NIR, 1064nm 1” diameter     NIR1064NDSET    one of each: OD 0.2, 0.5, 0.7, 1.0, 2.0 $395


NIR, 1550nm 1” diameter     NIR1550NDSET    one of each: OD 0.1, 0.3, 0.4, 0.5, 1.0 $395
