Digital Neutral Density Filters

nnnn

Jenoptlk offers Digital Neutral Den-

nnnn

sity Filters for precise transmission

nnnn

control.

nnnn

Digital neutral density filters contain

nnnn

well-defined metal absorber micro-

nnnn

structures that are randomly dis-

nnnn

tributed on a fused silica substrate.

nnnn

Density and size of the structures

nnnn

can be customized to meet precisely

nnnn

the transmission profile required by

nnnn

the application.

nnnn

Individual Digital Neutral Density Fil-

nnnn

ters according to customers require-

nnnn

ments can be supplied within two

nnnn

weeks.

nnnn

Features:

nnnn

• Well-defined 1-or 2-dlmenslonal

nnnn

transmission profiles

nnnn

• High accuracy of transmission

nnnn

• High damage threshold

nnnn

• Broadband attenuation for DUV

nnnn

to IR wavelengths

nnnn

• Large clear aperture

nnnn

• Optional AR coating with excel-

nnnn

lent homogeneity

nnnn

• Custom designs with short

nnnn

delivery time

nnnn

Applications:

nnnn

• Precise correction of intensity

nnnn

profiles in illumination or

nnnn

projection systems

nnnn

• Compensation for transmission

nnnn

profiles of individual optical

nnnn

systems

nnnn

• Variable attenuation filters for

nnnn

high-power lamps and expanded

nnnn

lasers beams

nnnn

• Soft edge apertures
