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
