Common Features

  • Diffraction-Limited Performance for Beam Diameters up to 70% of Clear Aperture
  • Long Working Distance
  • Large Entrance Aperture of >5 mm
  • Infinite Conjugate Design
  • RMS-Threaded Housing
  • Air-Spaced Design

These all-refractive UV Achromatic MicroSpot Focusing Objectives are designed for use with UV excimer lasers and other ultraviolet sources. The lens elements in these objectives are made from the highest quality, lowest absorption, excimer-grade fused silica and CaF2 available. These lenses are available with either narrowband or broadband AR coatings (see the Specs tab for details).

Our microscope objectives can be mounted directly to our fiber launch systems, or they can be mounted to any of our flexure stages using a HCS013 RMS mount. Alternatively, these microscope objectives can be easily mounted in our cage system, lens tubes, or other SM1 compatible optomechanics using an SM1A3 adapter.

c Effective Focal Length - Please note the effective focal length (EFL) changes with wavelength and is specified at the operating wavelength.
d Numerical Aperture
e Theoretical Focal Spot size assuming the entrance aperture is filled and the input beam profile is Gaussian.
f Entrance Aperture
g Using the LMU objectives outside of the AR coating range is not recommended because of surface reflections that can create ghost images and significantly reduce the overall transmission through the optic.

  • AR Coated for 240 – 360 nm or 325 – 500 nm
  • 5X, 20X, or 40X Magnifications Available
  • 0.14, 0.40, or 0.50 Numerical Apertures

These 5X, 20X, and 40X objectives are based on an optical design for broadband use that minimizes the focal shift as wavelength changes. Due to this design, they are ideal for focusing or collecting polychromatic light, making them better suited for use in spectrometry, wafer inspection, medical applications, or any other application where a broadband source must be focused.

  • AR Coated for 240 - 360 nm or 325 - 500 nm
  • 3X, 10X, or 15X Magnifications Available
  • 0.08, 0.25, or 0.32 Numerical Apertures

These 3X, 10X, and 15X objectives have a narrowband optical design, which is best for deep UV applications and micromachining. They have a broadband coating, making them ideal for sharply focusing one wavelength, while allowing other wavelengths to be transmitted slightly out of focus. We also offer narrowband-coated versions of these objectives below.
