OPTAplus designs and manufactures custom spherical lenses. Both surfaces of spherical lenses feature a spherical shape, they are defined by sections of a geometrical sphere.OPTAplus’ custom spherical lenses are available as plano-concave or plano-convex types, either spreading or focusing the beam of light, but also in bi-convex or bi-concave shapes. Further versions available are doublets and triplets.OPTAplus is capable of manufacturing spherical lenses in dimensions ranging from 2.0 mm up to 250.0 mm or even bigger on customer request. Available materials are optical glass, quartz glass, Borosilicate glass and colour-filter glass, as well as crystals like Si, Ge, MgF2, CaF2, Sapphire and others.On customer request, OPTAplus’ custom spherical lenses can be coated with a broad selection of coating materials for the NIR, VIS and UV range for single wavelength or spectral area:Anti-reflection (AR) Coatings: Single-layer AR Coating, V-coating and Multi-layer CoatingReflective Coatings: Metallic and Dielectric CoatingPolarizing Coating Please contact the AMS Technologies optical lens experts to discuss your customized spherical lens solution that exactly matches your application’s requirements.Applications: Measurement & Control; Medical; Laser; Engineering; Sensors; Machine Vision; Image Processing; Aerospace & Defense; Other

Standard Peltier Elements Peltier elements from Anvelt are solid-state thermoelectric modules designed for precise, reliable temperature control in industrial and scientific applications. Based on the thermoelectric effect, these modules generate a controlled heat flow when powered by direct current, enabling both cooling and heating without moving parts, refrigerants, or mechanical wear. Anvelt draws on long-standing expertise in thermoelectric manufacturing to deliver products that combine stable performance, mechanical robustness, and a high degree of design flexibility.Anvelt Peltier elements are engineered to support efficient thermal management across a wide range of operating conditions. Their construction is based on proven thermoelectric semiconductor materials, durable ceramic substrates, and reliable internal interconnections. This ensures predictable electrical and thermal behavior over extended service life, even under continuous operation. With a portfolio that includes standard designs as well as application-specific configurations, Anvelt Peltier elements are suited for both development projects and series production in demanding environments.Key features• Solid-state Peltier elements for cooling and heating without moving parts • Single-stage and multi-stage configurations for different temperature differentials • Wide range of standard sizes, geometries, and electrical ratings • Custom designs available for specific dimensions, power levels, and operating conditions • High-quality thermoelectric materials with stable electrical characteristics • Robust ceramic substrates for mechanical strength and thermal stability • Consistent unit-to-unit performance through controlled manufacturing processes • Low maintenance requirements and long operational lifetime • Suitable for continuous operation in industrial and laboratory systems ApplicationsAnvelt Peltier elements are used in a broad spectrum of applications requiring controlled heat transfer and precise temperature stabilization. In analytical and laboratory equipment, they support temperature regulation of detectors, sensors, and sample holders. In photonics and optoelectronics, Peltier elements are applied to stabilize laser diodes, optical assemblies, and imaging sensors, where thermal drift can directly affect performance.Industrial electronics benefit from localized cooling of components exposed to high thermal loads or fluctuating ambient conditions. Additional applications include environmental monitoring devices, compact refrigeration systems, medical and diagnostic equipment, and specialized enclosures requiring compact thermal control. Due to their solid-state design, Anvelt Peltier elements are well suited for mobile, orientation-independent systems and vibration-sensitive environments where compressor-based cooling is unsuitable.The combination of compact form factor, precise controllability, and scalable performance makes Anvelt Peltier elements a versatile solution for modern thermal management challenges across research and industrial sectors.What’s next?Selecting the appropriate Peltier element requires careful consideration of heat load, target temperature range, electrical supply, and heat dissipation strategy.
