Payment

What payment methods do you accept?

We accept common online payment methods, including credit card, Apple Pay, Google Pay, and other available checkout options.

Can I cancel my order and get a refund after payment?

Yes. If you contact us within 1 day after placing the order, the payment can usually be refunded before the order is processed.

Please contact us at admin@fulteng.com as soon as possible with your order details.
Shipping

How long does shipment take?

Order preparation usually takes 3–5 working days before shipment.

After the order is shipped, international delivery usually takes around 3–10 days, depending on the destination country and local delivery process.

How will my order be delivered?

We use e-commerce logistics to deliver the order to you.

The general process is:

  1. Order processing — payment is checked and stock is confirmed.
  2. Packing — the product is picked, packed, and prepared for shipment.
  3. Carrier hand-off — the package is passed to the logistics provider.
  4. Last-mile delivery — the local courier delivers the package to your address or collection point.

When will I receive the tracking number?

The tracking number is usually available only after the package reaches the last-mile courier stage.

This means tracking may not appear immediately after the order is packed or shipped.
Return policy

Can I return a standard product?

Yes. Standard products can be returned for any reason within 7 days after you receive the goods.

Please note:

  • The item should be returned in its original condition.
  • The return shipping cost is paid by the customer.
  • The standard return shipping cost is USD $35.

Can I return a custom product?

Custom products are made or prepared according to your specific requirements, so they usually cannot be returned.

Custom products can only be returned or handled if there is a confirmed quality problem with the product.

Star Targets are designed for evaluating focus, resolution, distortion, and imaging performance in optical systems. Each model uses a single selectable Model option describing material, size, wedge angle, sector number, diameter, and accuracy.

Available glass models include 10°, 6°, 5°, and 3° wedge-angle designs with sector counts from 36 to 120.

What is a Star Target?

Siemens star charts are based on black and white areas. For resolution measurements (according to ISO 12233), the variation between black and white areas displays a sinusoidal shape.

Each star in the image provides many different frequencies, such as low frequencies at the outer radius and high frequencies at the inner radius.

How to use a Star Target?

The center of the test card is covered by a registration mark for software-based automated detection. The radius of each star modulation is examined by software. The results are combined to form a graph called the MTF curve. The same frequency is measured at 25 points in the image. This measurement is always objective.

What information can we get from MTF Curve?

The system's limiting frequency. The resolving performance of the camera from low to high frequencies. Image sharpness during image processing. Resolution can be checked in several diagonal directions, both horizontally and vertically.
