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

Multi-Stage Thermoelectric ModulesImax 2.8-9.5 A; Qmax 10-59 A; Vmax 5.27-15.8 V; ΔTmax 83-86 KMulti-stage thermoelectric modules from S&PF MODUL are engineered for solid-state cooling applications that require significantly higher temperature differentials than single-stage solutions can provide. By stacking multiple Peltier stages in a cascaded architecture, these modules enable deep cooling while retaining the inherent advantages of thermoelectric technology, including precise control, mechanical robustness, and maintenance-free operation. With more than 30 years of experience in thermoelectric design and production, S&PF MODUL delivers multi-stage modules with predictable performance and long-term reliability for scientific and industrial use.The multi-stage design allows each thermoelectric layer to contribute incrementally to the overall temperature drop, making these modules suitable for applications that demand low cold-side temperatures under controlled heat loads. High-quality semiconductor materials, durable ceramic substrates, and stable internal interconnections ensure consistent electrical and thermal characteristics, even during continuous operation or repeated thermal cycling. The portfolio includes a wide range of stage counts, form factors, and power ratings to support flexible system design. Key features• Cascaded multi-stage Peltier architecture for high temperature differentials• Designed for deep cooling beyond the limits of single-stage thermoelectric modules• Wide selection of standard configurations with varying stage counts and cooling capacities• High-grade thermoelectric semiconductor materials with stable performance• Robust ceramic substrates and metallization for long-term mechanical and thermal reliability• Customization options for dimensions, electrical parameters, and lead layouts• Low thermal resistance interfaces for efficient coupling to heat sinks or liquid cooling systems• Controlled manufacturing processes for reproducible unit-to-unit performance• Suitable for continuous operation in precision cooling environments ApplicationsS&PF MODUL multi-stage thermoelectric modules are used in applications where extended temperature differentials and precise thermal control are essential. Typical use cases include cooling of infrared detectors, CCD and CMOS sensors, and other highly sensitive components in analytical and imaging systems. They are also employed in spectroscopy, laser diode stabilization, and scientific instrumentation that operates at reduced temperatures to improve signal quality and measurement accuracy.Additional applications include cryogenic pre-cooling stages, compact laboratory refrigeration units, environmental simulation equipment, and advanced test systems in aerospace, telecommunications, and automotive development. In these contexts, multi-stage thermoelectric modules provide a compact and reliable alternative to compressor-based cooling technologies, particularly where vibration-free operation and fine temperature control are required. What’s next?Achieving optimal performance with a multi-stage Peltier module requires careful consideration of heat load, target temperature differential, electrical supply, and heat rejection design.
