Linear Actuator and Types of Linear Actuators
A linear actuator is defined as a machine or a combination of various tools that can create linear force and motion with the use of an externally applied energy source. These are very useful devices that play a significant role in different fields including consumer products, medical equipment, furniture, hobby design, etc. These can be used for all products where automation is required. The devices are available in a wide assortment of size, force and speed. Customers can choose the one that suits their business requirements and budget.
As far as the types of the linear actuators are concerned, these are of different types. Some of the major ones have been discussed below:
Mechanical
Mechanical linear actuators work by converting the rotary motion into linear motion. Various mechanisms are used for making this conversion. As far as the use of these actuators is concerned, they are widely used in the field of lasers and optics for manipulating the position of rotary stages, linear stages, goniometers, mirror mounts and various other positioning instruments.
Hydraulic
Hydraulic actuator is also known as hydraulic cylinder. This device includes an empty cylinder with a piston inserted into it. For achieving a controlled accurate linear displacement of the piston, its both sides are pressurized and de-pressurized alternately. One of the common examples of a physically operated hydraulic cylinder is a hydraulic car jack.
Electro-mechanical
These are similar to the mechanical actuators. The only difference is that in place of a control knob or handle, there is an electric motor.
Pneumatic
Also famous under the name of Pneumatic cylinders, these devices resemble hydraulic cylinders. The only difference is that they use compressed gas for providing pressure instead of using a liquid.
Piezoelectric
Piezoelectric actuators are capable of achieving extremely fine positioning resolution but they have a very small range of motion. In addition to this, piezoelectric materials show hysteresis. As a result, it becomes difficult to control their expansion in a repeatable way.
These are some of the major types of actuators used in various fields for making the task a lot easier. You can grab the one that suit your budget and needs best. There are a number of companies that have been offering these devices in different sizes and affordable rates for enhancing productivity. These days, most of the companies have their own dedicated sites and offer products online to facilitate customers in a better way. You can easily place an online order for any of your favorite product.

How to film through a car window without a glare?
I'm shooting a car seen in about a week with a dvx100b. When i shoot at the window, there is an awful glare that I don't want. How can I get rid of that?
My setup is a dvx100b with a tiffen uv filter and a tiffen linear polarizer. The camera is mounted on the hood pointing at the passengers.
Try shooting during times when the sun is at it's lowest. You can even try at another angle.
Good Luck
