Befort – Achromats of our standard program are characterized by specific selection of the glass type realization integrated in the optics reflex reducing (AR) coating high UVresistance All Achromats are available with black anodized aluminum mounts. The adjustment of the AR coating to other wave length ranges is possible, optionally, air spaced achromats for extreme UV applications are available. We offer our customers a graded standard program with a diameter

Differentiation between ANSI and DIN / EN ANSI eyeglass blinds differ from DIN / EN eyeglass blinds in terms of pressure levels, sealing strips and materials. In German-speaking countries, glasses blind disks are also called blind disks or throttle disks. However, the English terms “spectacle blind”, “blind paddle” are also often used in Germany. Pressure ratings according to ANSI in lbs The following pressure levels for blind disks according to ANSI are available 150, 300, 600, 900 and 1500 lbs. Sealing strips The following forms of sealing strips are available: SMF, FF, RF and RTJ. Materials The steel materials A 516 GR 60 and A 516 GR 70 are available. In the stainless steel sector, the materials TP 304 / L, TP 316 / L and TP 312 are possible.

Reflectionreducing coatings increase the light transmission of optical systems. This is particularly important for the light intensity of multilens optical systems such as objectives. Another benefit of antireflection coatings is their capability to strongly reduce scattered light losses between the lenses. Our product portfolio covers single and multiplelayer antireflection coatings, antireflection coatings for laser applications and coatings for applications in ultraviolet (UV), visual (VIS) and infrared (IR).

At Befort, spherical precision optics pass through the hands of qualified specialists. They work with a sure instinct and stateoftheart technology. The machine processing of each surface is done on CNC grinding and polishing machines. We produce spherical precision lenses from optical glass, quartz glass and radiationresistant materials with diameters from 3 mm to 130 mm and a curvature radius from 1.18 mm to plane. We make individual lens elements, achromatic systems, concave mirrors, cylinder lenses and other precisely fitting glass geometries to suit your specific application.
