LASER FOCUSING LENS

Laser Focusing Lens

What is focusing lens?

The focusing lens is the last optical device in the laser path. laser focusing lenses The anti-reflective coating on the surface of the focusing lens is made of zinc selenide (ZnSe), and the focusing lens is usually a plano-convex lens or a curved lunar surface lens. To ensure efficient laser operation, the choice of lens is critical. The type used for each machine is usually indicated in the machine manual. The laser focusing lens is used to focus the collimated light from the laser beam in various laser applications. Laser lenses include a variety of optic lens types, including PCX lenses, aspheric lenses, cylindrical lenses or laser generator lenses. Laser lenses are designed to focus light in several different ways depending on the lens type, such as focusing down to a point, a straight line or a ring. Many different types of lenses can be used in the wavelength range.

Xi'an Huaxing Bofa shares with you about the scanning range of laser focusing lens, hope it will be helpful for you.

What is the role of laser focusing lens?

The diameter of the laser beam used by the laser cutting and engraving machine is approximately one-quarter of an inch (240 one-thousandth). In order to achieve high-quality engraving and precise cutting, the laser beam uses a mirror and focusing lens system to redirect the laser.

The laser system uses a plano-convex lens to focus the laser. The laser enters the convex lenses and starts to converge to a focal point. After passing through the focal point, the light diverges again.

How does a laser lens work?

The steering mirror directs the laser beam to and allows for the movement of the head and gantry transport system. Laser mirrors are designed with a high degree of reflectivity for specific wavelengths or wavelength ranges using a variety of high ware, coatings or a combination of both.

Our optical systems offer a wide range of laser lenses for a variety of laser focusing needs. Different lens types will have different spot sizes, different focal depths (focal tolerance) and different focal lengths producing different results. The focus tolerance (depth of focus) is the area with the smallest beam diameter. The larger the lens, the longer the focal tolerance. The shorter the focal length of the lens, the faster the convergence/divergence, the smaller the focal spot, and the shorter the depth of focus. So the finer the graphic, the smaller the lens should be. When we cut thicker material, it is recommended to use a larger size lens.

Some cautions you need:

1. The output wattage of the laser device.

2. Use and purpose (cutting or engraving).

3. The fineness of the graphic.

4. The thickness of the material to be cut or engraved.

5. The level of resolution.

6. Regarding custom products, we can customize the size of the product, etc.

7. If it's not dirty, please don't clean it! If cleaning is required, use lens paper with solvent to clean the optical lens in a low dust and clean environment.

We offer a wide range of standard and special optic laser lenses, laser goggles, etc. Contact us to ensure the best fit for your laser cutting machine.

We will precede the purchaser in detail Communicate and customize Aluminum Die Cast Mold Accessories according to the buyer's wishes.

Aluminum Die Cast Mold Accessories production process

A die-casting mold or mold is a closed container in which molten metal is poured into the mold or mold under high pressure and high temperature, and then rapidly cooled until the solidified part is hard enough to allow ejection from the mold.

Tooling

The mold or die-casting mold is made of alloy tool steel and is divided into at least two parts, the fixed half (top cover half) and the movable half (extruder half) to allow the casting to be removed. The mold may also have movable sliders, cores, or other parts to create holes, threads, and other desired shapes in the casting.

Opening

Holes in the fixed mold half allow molten metal to enter the mold and fill the cavity. Half of the ejector usually contains a runner (channel) and a gate (inlet) that guide the molten metal to the cavity. The mold also includes a locking pin for fixing the two halves, a thimble to help remove the casting, and an opening for a coolant to help cool the mold and solidify the molten metal.

A very important accessory required to run any die casting mold is called the "jet sleeve". The injection sleeve is a hollow tube. When it is put into the die-casting machine, it will be inserted into the fixed half hole of the mold. The sleeve extends horizontally from the mold, and there is a small hole on the top of the sleeve, where molten metal is poured to prepare the plunger for injecting the metal into the mold. Shooting sleeves need to be replaced at certain intervals, which is very important for this process. Usually, when the mold is removed from the die casting machine, the Shot Sleeve is not sent with the mold, which causes trouble for the manufacturer, because it takes a long time to manufacture a new sleeve.

Making

The two mold halves are run in a die-casting machine that runs at the required temperature and pressure to produce high-quality parts that meet the customer's requirements for the final shape or close to the final shape. When the die casting machine is closed, the two mold halves are locked and held together by the pressure of the machine. The surface where the ejector and fixed half of the mold meet and lock is called the "mold separation line". The total projected surface area of the cast part measured at the mold parting line determines the clamping force of the machine.

In order to work in this environment for a long time, the die-casting mold must be made of high-quality tool steel with strict specifications, and be heat-treated to achieve the required hardness and structure (therefore, there are NADCA guidelines), and have a mold and cavity The size is processed to strict specifications.

The customer's product design requirements directly affect the size, type, function and cost of the required tools. The items involved in the processing decision include the number of cavities, the number of cores or sliders, the weight of the mold, machining, completion requirements, polishing and electroplating, etc.
