Characteristics of Research Optical Contact Angle Technology

The research-oriented optical contact angle meter is the result of a comprehensive analysis of the advantages and disadvantages of various optical contact angle measuring instruments, combined with the long-term research and production experience of Pinzhi Chuangsi, to leverage strengths and avoid weaknesses. With the design intention of cost control and performance improvement, we have comprehensively optimized the mechanical structure, optical system, and software design of each part, ensuring the stability of control and high clarity of imaging.

Research Optical Contact AngleMore precise, stable, and diverse control systems

1. The core optical machinery adopts cross linear guide rail technology, and the design accuracy can reach 0.01mm manually. When controlled by software, the accuracy can fully reach 0.5um;

2. Provide mechanical structure design with up to 10 dimensions (2XYZ rotation and 3 horizontal adjustments) to coordinate and control the operation of the sample stage, camera, injection system, and droplet titration system.

3. Optical mechanical control has no longitudinal movement and higher stability.

4. A professional level high-precision injection pump system, with a low droplet control accuracy of up to 0.02uL or even nL, can be used for high-precision repetitive positioning injection.

5. The micro distance needle movement and focusing control system provides more precise and convenient droplet transfer operations, especially suitable for controlling the transfer of droplets between the needle and solid materials during superhydrophobic material testing.

6. The integrated design of the whole machine, with the host made of high-grade aviation aluminum, ensures the portability of the whole machine on a solid foundation.

More specialized and humanized mechanical structure design

1. The unique fixed focal length mechanical structure, combined with a precision adjustment frame, can more conveniently and accurately find the focal length and capture clear images.

2. The unique integrated rolling platform design allows the sample to rotate together with the lens, which is more conducive to maintaining the center point during the sample observation process. There is no laborious swinging of the whole machine, nor is it inconvenient to control the rotation of only some parts, which brings the possibility of more accurate analysis of the roll off angle for you. Meanwhile, through simple replacement, the lens can also be kept from rotating while the sample stage rotates.

3. Unique shading film design, clearer background light, and better imaging effect.

4. The unique replaceable injection system design can hold our professional injector, as well as fine needle tubes, PTFE head needle tubes, or needle tubes specifically designed for testing hydrophobic materials or testing medium to high viscosity samples.

5. Up to 4 horizontal adjustment system designs: Based on the adjustment of the overall machine level and lens level, we specifically provide high-precision two-dimensional horizontal adjustment function for the sample stage, ensuring that the horizontal line of samples with poor flatness can be found.

6. The dual level adjustment system combining software and hardware provides the possibility for you to better find the horizontal line.

Mechanical horizontal structure combined with adjustable brightness LED cold light source system and CAST ™ The 2.0 software system provides a strong guarantee for you to better find the horizontal line. At the same time, it is more convenient to measure the roll off angle and forward/backward angle.

A clearer and faster optical imaging system

1. Adjustable brightness LED cold light source technology provides the possibility for you to obtain clearer droplet contours, while also effectively avoiding the evaporation of small droplets caused by additional heat.

2. Using the original German 87 frames per second camera (standard WVGA format) to capture higher quality images. (Optional 130M, 300M, 500M resolution cameras)

3. High magnification, high depth of field industrial continuous magnifying lens, with an optical magnification of 0.35-4.5X.

4. Adopting the USB2.0 standard interface, it has faster speed and higher compatibility, and can connect laptops and newly designed desktop computers without the inconvenience and incompatibility of opening the computer case and inserting cards.

5. High speed cameras with AOI technology can achieve speeds of up to 100-300 frames per second, 1000 frames per second (optional), or even higher.

6. Choose a GigE camera for faster and more stable transfer speed.
