Optical Lens Coating Machine

Optical lens coating machines are essential core equipment for the modern optical industry.

The physical vapor deposition process under high vacuum, combined with precise film thickness monitoring, makes it possible to controllably grow thin films on the lens surface that meet a variety of stringent optical and physical requirements, greatly expanding and optimizing the performance and application range of optical components.

Optical lens coatings have a wide range of applications, covering almost all optical components and systems that need to utilize or control light.

 

Eyeglasses
Anti-reflective film:

Reduces reflected light on the lens surface, improves light transmittance and visual clarity, reduces glare, and is beautiful (makes the lens look more transparent).

 

Waterproof/anti-oil film:

Prevents water droplets and oil stains from adhering and is easy to clean.

 

Hard film:

Improves the surface hardness of resin lenses, enhances wear resistance, and prevents scratches.

 

Anti-blue light film:

Selectively filters some harmful blue light.

 

Polarized film:

Used for sun lenses to reduce reflected glare on non-metallic surfaces (water surface, road surface).

 

Dye film:

Achieve the color of the lens.

 

Camera, camcorder, telescope, microscope lens
Broadband anti-reflection film:

Greatly improves the transmittance of the entire visible light band (even extended to ultraviolet and infrared), reduces glare and ghosting, and improves imaging contrast and clarity. Multilayer film design is the key.

 

Beam splitter film:

Splits incident light into reflected light and transmitted light in a specific proportion (such as a beam splitter prism).

 

Filter:

Selectively transmits or reflects light of a specific wavelength (bandpass filter, longpass filter, shortpass filter, notch filter).

 

Infrared cutoff filter:

Blocks infrared light from entering the sensor to ensure color imaging accuracy.

 

Protective film:

Improves the wear resistance and anti-fouling ability of the front lens.

Optical communication
Wavelength division multiplexer filter:

Realizes the combination and demultiplexing of multiple optical signals with different wavelengths.

Optical fiber connector end face anti-reflection film:

Reduces end face reflection loss.

Medical and biological instruments
Endoscope, microscope objective lenses:

high-performance antireflection coating.

Biochemical analyzer filters:

Bandpass filters for specific wavelengths.

Laser therapy equipment:

Special coatings on reflectors, focusing mirrors, and protective mirrors.

Industrial Sensors and Measurement:
Filters, spectrometers, and reflectors in various spectrometers, interferometers, and sensors.

Lighting
Cold light mirror:

Reflects visible light and transmits infrared thermal radiation (used in stage lights, projection lights, etc. to reduce the temperature of the illuminated object).

The high-precision optical lens coating machine is equipped with a quartz crystal film thickness meter and an optical film thickness automatic control system. It uses PLC and industrial computers in conjunction with the independently developed PY3100 system to achieve full automatic control of the entire working process, which can be unattended, thereby improving work efficiency and ensuring the consistency and stability of product quality.

The high-speed vacuum system is equipped with a cryogenic device and excellent dynamic vacuum capability, providing the necessary vacuum conditions for the preparation of complex optical film systems.

The E-type electron gun with stable evaporation distribution and reliable performance and the optimized positional relationship between the evaporation source and the workpiece holder ensure the evaporation distribution of the film material for the realization of the precision film system.

The stable and high-speed rotating system of the workpiece rack makes the product spectrum curves of the inner and outer circles of the workpiece rack more consistent.

Suitable for use in the optical industry and large-scale industrial production with high-end requirements.
