Optical Interface Adaptation

Adapter Type	Coverage Range	Highlights
Universal C-Mount Reduction/Magnification Adapters	23.2 mm microscope eyepiece tubes, 31.75 mm telescope eyepiece tubes → C-Mount, magnification 0.37×–1× adjustable/fixed	Manual focusing, parfocal adjustable with objectives, compatible with 1/4″–1″ sensors, complete field of view without dark corners
Global Brand TV Interface Adapters	Olympus, Zeiss (P95 & 60N), Leica, Nikon, Huvitz, Labomed and other trinocular photo tubes → C/T2/M52	Built-in 0.35×–2.25× reduction lenses, CNC precision-machined housings, peak contrast reaching diffraction limit, lens entrance pupil perfectly matched to original optical path
Eyepiece Tube Adapters	23.2 mm → 30/30.5/30.75 mm	One-step extension of 23.2 mm adapters to large eyepiece tubes, convenient for teaching microscope retrofitting

Mechanical Positioning & Stands

TPS-Series Heavy-Duty Column Stands: Flexible combination of brackets and bases, large focus knobs with durable steel gears, compatible with 50 mm/76 mm bodies and continuous zoom objectives, maximum base 380×250 mm

M-SD-HM1-5 Portable Stand: Rack and pinion focusing mechanism, lightweight and robust anodized aluminum construction, 60–110 mm focusing travel, suitable for USB portable digital microscope field sampling

Continuous Zoom Objectives

The TZM series is a 100% pure mechanical structure long working distance continuous zoom objective that achieves stepless smooth zooming through high-precision worm gear and ball bearings. Without any motors or encoders, it can rapidly switch magnification within 0.4×–8×/0.6×–12× to 1×–16× (optional) ranges while maintaining parfocal throughout the entire field of view.

Core Features

Power-free operation: Both zoom and coarse/fine adjustment rings use pure mechanical transmission

Parfocal optics: Focus position remains virtually unchanged during magnification

Long working distance: Standard 95 mm, optional 160 mm LWD version

Large zoom ratio: 8:1/12:1/16:1 three ratios available

Durable construction: 100,000 zoom cycles without loosening

Industry Application	Application Examples	Value Highlights
Electronics Manufacturing	SMT solder joints, BGA solder balls	Manual ring switching
Precision Machinery	Tool wear, gear burrs	Long working distance + large depth of field
Jewelry & Watchmaking	Setting prongs, gear rivets	0.2×–32× extended magnification

Optical Lens Systems

🔴 Short-Wave Infrared (SWIR) Lenses
