What are powell lenses?

Powell lenses can fan out a collimated beam in one dimension, which have the shape of  the prisms with a roof and are often used to convert the laser beam into a uniform illumination line. Cylindrical lenses can also transmit, but are less effective, with faded edges and a hot spot in the center.  Powell lenses, on the other hand, produce a straight line with a uniform energy distribution and light is evenly distributed along the line. Although there are other methods for uniform laser illumination, the powell lens is so far the most powerful and flexible method for achieving this goal.

Powell lens purchasing guides

Things you must know before you make a decision to purchase your powell lenses.
Do you offer free samples for testing?

Yes. We can provide free samples for testing on two conditions: 1. The cost of the sample is not too high. 2. The quantity is not more than 3 pieces.
Sometimes we charge the sample fee up front, but when the customer places an order this fee is deducted. This is still equivalent to giving the customer free samples.

How do you ensure your product quality?

The optical lenses used in each project are made by a small team. Each worker is responsible for his grinding, polishing, chamfering, coating, etc. Everyone has a smooth handover and do not hand over defective products to the next process. An interferometer is placed in the workshop to quickly check the quality of the product on site.

How can you ensure your lead time ?

We plan precisely to ensure that each shipment is delivered on time. Even if we cannot deliver on time due to force majeure, we will inform our customers in advance.

How do you handle a customer complaint?

If it is our responsibility, we will cover 100% of all costs. If the customer is also responsible, we will also do our best to help come up with a solution.

If the optical lenses are damaged in delivery, how do you fix it?

First of all, the probability of such a thing happening is extremely low. If unfortunately it happens, then sorry, we will send you the brand new optical lenses free of charge.

Can you do door-to-door service?

Door-to-door service is available for all the products we make, except optical lenses. Just tell us what you need and we give you a one-stop service.
