A pig crafted from 80,000 succulents stands quietly on a street corner in Hangzhou.
People pass by.

Some keep walking.

Some stop… just for a moment.

Because it feels like the city itself.

Spring in Hangzhou:

soft, vibrant, quietly alive.

A place where imagination

turns the ordinary into something unforgettable.

Where people pause

not because they have time,

but because beauty makes them.

We are CONTRASTECH.

Born in Hangzhou.

Inspired by its creativity.

Bringing precision imaging

and machine vision

to industry and science.

The poetry of Hangzhou lives in what we create.

The strength of Hangzhou drives what we do.

☀️ Sunlight Protection vs Burn Protection — What’s the difference?

Some users ask:
Are “sunlight protection” and “sensor burn protection” the same?

Not exactly.

👉 Sunlight protection
Helps reduce overexposure under strong light

👉 Burn protection
Prevents permanent damage from intense light (like lasers or direct sun focus)

In short:
One protects your image quality
The other protects your sensor

Choosing the right protection depends on your application.

Have you faced sensor damage in your system?

📷 How much detail is enough?

With up to 604MP resolution, Contrastech large area scan cameras capture extreme detail for demanding inspection tasks.

✔ Ultra-high resolution (up to 604MP)
✔ Stable imaging with TEC cooling
✔ Built-in buffer for smooth data flow
✔ Multiple interfaces: USB3.0 / GigE / 10GigE / CXP

Designed for applications where every pixel matters.

When small defects matter, resolution makes the difference.

⚡ Why use a line scan camera instead of area scan?

Line scan cameras capture images line by line — perfect for continuous, high-speed inspection.

Contrastech Line Scan Cameras offer:

✔ 2K / 4K / 8K / 16K resolution
✔ Color & Mono options
✔ Stable, high-speed imaging

Widely used in:
📦 Sorting
📄 Web & paper inspection
🧵 Textile
🔍 PCB & surface inspection

If your objects are moving fast, line scan is often the better choice.

What’s your inspection challenge?

Hyperspectral Imaging for Handwriting vs Printed Text Identification
Traditional calligraphy authentication relies heavily on expert experience and visual inspection, which can be subjective and inconsistent.
Using a 400–1000 nm hyperspectral camera with push-broom scanning, we analyzed the spectral curve characteristics of handwritten and printed text.
• Printed text shows smooth spectral curves with no characteristic peaks
• Handwritten text presents clear spectral feature peaks due to ink deposition and stroke structure
• Hyperspectral imaging provides objective and non-contact identification
This method enables scientific and reliable discrimination between genuine handwriting and printed reproduction.
