Abstract
•Hot embossing fabrication of mini refractive lenses made from soft glasses.•Investigation of glass selection criteria: transmission window, resistance to crystallization, adhesion.•Selection of lead-bismuth-zinc oxide glass and hot embossing of demonstrator elements.
In this paper we report on the development of small-diameter lenses in soft glass with transmission in infrared till 5 μm using hot embossing method. A fused silica stamps and in-house synthesized tungsten–tellurium–niobate and lead–bismuth–galate glasses are used for replication. Optimization process of hot embossing is presented. Optical properties of replicated lenses were characterized. Resolution of 50 lp/mm is obtained.
