Micro Optics
Fast Axis Collimators (FAC)
- Collimation of the Fast Axis
- Acylindrical / aspherical cylindrical lens
- The first and most important optical component in the development and production of diode laser systems
- Free selection of high-quality glass
- Anti-reflective coating with lowest absorption for high-power applications, large numeric aperture allows the collimation of the entire diode power with best beam quality
- Best transformation efficiency for diode lasers thanks to high transmission and good collimation properties
Fast Axis Collimators (FAC)
Slow Axis Collimators (SAC) and Arrays
- Collimation of the Slow Axis for high-power diode lasers and fiber lasers
- Monolithic array of cylindrical lenses
- Low curvature deviation
- Consistently high optical quality for thousands of SACs from wafer-level production
- Free selection of high-quality glass
- Best transformation efficiency for diode lasers thanks to high transmission and good collimation properties
Slow Axis Collimators (SAC) and Arrays
Monolithic Collimators
- The monolithic collimator consists of a monolithic glass block with two oppositely crossed cylindrical surfaces having different focal lengths
- Simultaneously collimate the light from the fast and slow axes
- From the light of a single emitter to a symmetrical beam with an almost round far-field profile
- Ideal for light collimation of single emitters in the blue spectral range
Monolithic Collimators
Beam Transformation Systems (BTS)
- The BTS transforms the asymmetrical far field distribution of a diode laser bar into a nearly symmetrical beam parameter product.
- Equipped with anti-reflective coating to lower the absorption for high-power applications
- Applications: Collimation of free beam lasers; efficient fiber coupling for high-power diode laser bars; BTS made of fused silica optimized for highest power densities
Beam Transformation Systems (BTS)
Fiber Couplers
- The fiber couplers allow the light from a single emitters / multi-emitters coupling to a single fiber with only one lens element
- The fiber coupler consists of a monolithic glass block with two oppositely crossed cylindrical surfaces and mounting surfaces
- The light of the fast and slow axes is collimated by one cylindrical lens to produce an almost symmetrical focus
Fiber Couplers
Wide Angle Diffusers (WAD)
- Our diffusers are manufactured with high refractive index glass material, which can diffuse laser beam in one direction with wide FOV angles up to 160°
- Using refractive optical element (ROE) technology, NO zero-order, NO “hot spot”
- Transmission efficiency > 95% (AR coated)
- Provide solutions in LiDAR systems that shape the laser beam into a steep slope of angular intensity distribution with uniformity as high as 90%
Wide Angle Diffusers (WAD)
Homogenizers (HOM)
- Homogenizers can handle a wide range of field geometries and beam shapes - top hat, rectangular, square and lines
- Homogeneity up to the technical limits (up to 1% non-uniformity)
- High NA, high fill factor and retention of polarization
- Optical efficiency of up to 90 % helps to cut the cost of expensive laser energy
- Manufactured from high-quality materials, e.g., fused silica, CaF2, suitable for many different laser sources (e.g., excimer laser, solid-state laser, diode laser)
- Customized freeform surfaces with the highest precision on different wafer sizes (up to 300 mm)
Homogenizers (HOM)
Compact Beam Shaper (CBS)
- Compact design with integrated high-grade micro-optics generates line-shaped or square laser beams. Each of these two beam geometries is available in various sizes
- The latest Focuslight beam shaping module provides a budget-friendly way to complement basic equipment for laser application development, in both scientific and industrial fields
- The features of the CBS: slim-design aluminum housing (diameter of 30.5 mm; 80 mm long); inhomogeneity across the entire area < 7.5%; line-shaped and square beam geometry; with SMA905 connection
