High-Precision Measurement Capabilities

Model VT 400H delivers unparalleled accuracy with magnification accuracy up to 0.15% and resolution of 0.001 mm. Coarse and fine focusing systems allow clear viewing, while the fine graduated glass screen enables precise measurement of profiles and angles. The high-contrast optical system further enhances measurement clarity, making it a standout choice for precision metrology applications.

Versatile and Reliable Construction

With a robust stage loading capacity of up to 5 kg, the VT 400H accommodates a wide range of sample sizes for both industrial and laboratory settings. The mechanical X-Y stage provides effortless sample positioning, and a 360 rotatable table with vernier scale ensures accurate angular measurements. Accessories such as the standard lens, spare bulb, and instruction manual empower long-term, reliable use.

Customizable & Efficient Illumination

Adapt your inspection process with vertical illumination as standard, and optional profile (contour) illumination. Leveraging an adjustable high-brightness 24V/150W halogen lighting system, users can fine-tune illumination and aperture to suit different inspection requirements. This allows detailed inspection even on challenging or reflective surfaces.

FAQ's of Vertical Illumination Profile Projector Model VT 400H:

Q: How does the VT 400H ensure precise measurements during use?

A: The VT 400H is equipped with a fine graduated glass screen with crosslines, high-contrast optics, coarse and fine focusing adjustments, and a mechanical X-Y stage with fine feed mechanism. Combined, these features ensure superior positional accuracy and measurement reliability to within 0.02% of the actual value.

Q: What types of samples or workpieces can be inspected with the VT 400H?

A: The VT 400H can handle workpieces up to 5 kg in weight and dimensions that fit within its 150mm x 100mm working area and 400mm screen diameter. It is suitable for both industrial and laboratory applications, particularly in precision metrology, toolmaking, and quality control tasks.

Q: When is it advantageous to use vertical versus profile (contour) illumination?

A: Vertical illumination (standard) is ideal for measuring flat or opaque objects, while the optional profile (contour) illumination is best suited for inspecting edge profiles or transparent items. The adjustable aperture and high-brightness lamp help optimize lighting for various inspection needs.

Q: Where can the VT 400H be installed and used effectively?

A: The VT 400H is designed for installation in factories or laboratories where precise, reliable optical measurements are essential. Due to its sturdy build (approx. 130 kg) and non-portable nature, it is best placed on a stable surface in a dedicated metrology or inspection area.

Q: What is the process for measuring angles and dimensions with the VT 400H?

A: Operators position the workpiece on the mechanical X-Y stage, bring it into focus using the coarse and fine focusing system, and align features on the graduated screen. Angle measurements can be made using the rotating table equipped with a vernier scale (1 reading) and protractor (1 resolution).

Q: How does the optional digital micrometer counter enhance the VT 400H's capabilities?

A: The digital micrometer counter allows for more precise displacement readings, enhancing dimensional measurement accuracy and simplifying the measurement process, especially for repetitive quality control tasks in manufacturing or laboratory environments.

Q: What are the primary benefits of using the VT 400H profile projector in metrology?

A: Key benefits include high accuracy (within 0.02% of measurement value), excellent image clarity via high-contrast illumination, versatile measurement tools (graduated screen, rotating table, digital micrometer option), and durable construction for consistent long-term use in demanding environments.
