Precision Optics for High-Power Lasers
Focusing Objective Lenses
DPM Photonics offers a variety of positive and negative air-spaced, fused silica, aplanatic lenses. These two- and three-element lenses are corrected for spherical aberration and coma to produce a diffraction-limited focus, at a specific laser line, with minimum wavefront distortion. Standard products include objectives for 266 nm, 355 nm, 532 nm and 1064 nm (other wavelengths are available by request). We welcome the opportunity to discuss or quote custom aplanat lenses.
Features
- High Power Handling (> 1 kW)
- Fused Silica Lens Elements
- Computer designed for best possible wavefront
- V-type coatings at 266 nm, 355 nm and 1064 nm
- Dual minimum coatings at 532 nm/1064 nm
- Positive lens elemens can be assembled in reverse order so focus is opposite threaded end (upon request)
Applications
- Focusing of industrial lasers (solid state, fiber-based, etc.)
- Collimation of divergent fiber laser output beams
- Materials Processing
