Precision Molded Glass Optics for Infrared

FISBA provides customized design of a variety of precision molded IR glass optics and manufacturing capabilities from prototype to high quantity serial production. Our molded chalcogenide glass aspheres are a cost effective alternative to germanium that does not suffer the effects of thermal darkening.

Technical Data:

• Wavelength: 1.2 – 14 µm
• Standard spec of 2 fringes irregularity at C.A. 25 mm
• Diameter: 2.5 – 50 mm
• Broadband AR and hard coatings

Micro optics

With diameters down to 300µm, our Micro Optics offer big performance for today and tomorrow’s solutions.

FISBA provides full services for microlenses from coating and centering to cementing and pre-assembly.  Easily integrated into optical assemblies, FISBA microlenses are available in various glass types and shapes (plano-convex, plano-concave and biconvex).

Micro Optics are not only used in Life Science applications but also for:

• Remote sensing
• Embedded vision systems
• Robotic Surgery

Customized microcameras

Custom and platform-based micro cameras for minimally invasive surgery and point-of-care diagnostics.

Leverage our extensive experience in micro camera design and production to accelerate your system development, reduce your risk, and enhance the performance of your solution.

Technical Data of an example:

• Diameter without illumination: 1.6 mm
• Diameter with illumination: 1.95 mm
• Length without illumination: ≤ 4 mm
• Length with illumination: ≤ 6 mm
• Field of view (diagonal): 120°
• Working distance: 5 – 50 mm
• Resolution: 400 x 400 px
• F-number: 6
• Wavelength: 400 – 700 nm
• Illumination concept: integrated illumination given by LED, directed through glass fibers from a separate control box

Customized optical systems

FISBA’s team is skilled in optical, mechanical and electronic design. We support customers in defining optical specifications for their unique        systems.

Our experience encompasses vision systems, assemblies for low light cameras, optical systems for microscopes, illumination systems, optical systems for lasers, athermalized and apochromatic imaging systems, and much more.
