Aspherical lens material
Depending on a wide range of optical materials for specific wavelengths, we can manufacture suitable aspheric lenses for our customers. Below some of the aspheric lens material is used for manufacturing.
Aspherical lens manufacturing, molded processing
Preparation of glass preforms
At present, the parts are generally required to be polished to a spherical surface.
Heating the preform
Heat the glass preforms and molds to the required temperature to bring the glass to a certain viscosity. The molding chamber is vacuumed or filled with hydrogen, nitrogen, or inert gas to prevent high temperature oxidation of the part.
Insert into the mold cavity for molding
Put the heated preform into the mold cavity, give the mold shell a certain pressure, so that the softened glass blanks in the mold cavity molding.
Make the mold cool down under the condition of constant load, and remove the load when the glass temperature is lower than the transformation temperature.
Cool down and take the part
After stopping the heating, continue to cool down to below 300°C and open the mold to take out the molded parts.
Glass molding annealing is to improve the degree of refractive index uniformity and improve the internal stress.

Aspheric lens purchasing guides
Things you must know before you make a decision to purchase your optical 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 aspheric 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.
