Technical Specifications

Precision Engineering for Optical Glass

Optical glass annealing demands exceptionally precise thermal management to eliminate internal stress while preserving optical clarity and refractive index uniformity. Sunny Furnace's box type annealing furnace addresses these critical requirements through:

• 9-Point Temperature Uniformity Testing — Every furnace is validated to maintain temperature deviation within ±3°C across nine measurement points, guaranteeing consistent annealing results throughout the chamber.
• Multi-Zone Heating Architecture — Multi-sided heating with electrothermal alloy wire elements ensures uniform heat distribution, eliminating cold spots that could compromise optical quality.
• PID Intelligent Program Control — Advanced PID algorithm enables precise, multi-segment temperature profiles with programmable ramp-up, soak, and cooling stages tailored to specific glass compositions.
• Touch Screen HMI & RS485 Communication — Intuitive touch screen operation combined with RS485 industrial communication protocol allows seamless integration with factory automation systems and remote monitoring.

Flexible Temperature Configurations

The furnace is available in four maximum temperature grades — 500°C, 700°C, 850°C, and 1000°C — enabling customers to select the optimal configuration for their specific optical glass formulations. Whether processing low-temperature specialty glasses or high-temperature borosilicate optical materials, the furnace delivers the precise thermal environment required.

Product Applications

• Precision annealing of optical lenses, prisms, and filters
• Stress relief treatment for camera and telescope optical elements
