Dielectric Mask

Contents


  • Introduction

  • Dielectric Reflective Mask

  • Transmissive Mask

Introduction

HOLO/OR has developed a series of projection masks to answer the demand of using such masks with very high powered laser sources in the UV-VIS spectrum. These masks have two different forms: the dielectric mask has a reflective coating that blocks unwanted light, and the transmissive mask uses a diffractive pattern that diffuses this unwanted light at large angles.

Typical Parameters:

Outer Diameter: 5 – 100 mm
Aperture Shape Round, square, multi-aperture, other
Aperture Size 10 um – 60 mm
Wavelength spectrum 193 – 11000 nm, each element designed for single wavelength
Transfer Region Small; sharp edges
SNR ~500
Shape size >5 um

Dielectric Reflective Mask

Dielectric masks are Fused Silica substrates patterned by very thin (~1um) reflective coating. The coated part reflects the incoming beam while the uncoated part transmits the beam.

Typical Applications:

  • Micro patterns projection for high power systems
  • UV lithography

Schematic sketch of the optical system:

Fig 1. Typical Set Up

HOLO/OR can design and manufacture a custom dielectric mask to match the customer’s needs.

Fig 2.Real measurement of custom Dielectric Mask taken with microscope magnification

Features of Dielectric Mask:

  • High damage threshold
  • Low absorption
  • High reflection (>99%) in reflective part
  • High transmission (>95%) in transparent part
  • Very thin dielectric reflective layer (~1 um)

Transmissive Imaging Mask

rinciple of operation:

The Transmissive Mask transmits all incident illumination without any blocking. The pattern to be imaged is a clear mask area that transfers the light without interruption, while the surrounding areas transfer light through a specially designed diffractive pattern which diffuses light in large angles. Placed close to the focal plane of a focusing lens, a pinhole blocks most of the diffused light, so that a high-contrast intensity shape is achieved at the image plane.

Schematic sketch of the optical system:

Features of Transmissive mask:

  • No danger of reflected light causing damage to optical system
  • ~100% transmission
  • Higher laser damage threshold than for reflective mask
  • Affordable price, similar to that of other diffractive elements
