Laser SystemsWe design custom miniature rotary solenoid assemblies for laser blocking shutters, safety shutters, ND (neutral density) filter actuators, and front surface mirror positioning. Our Optical Beam Shutters use an electro-mechanical rotary solenoid actuator to provide inherent “fail-safe” operation of the solenoid shutter assembly.

Thermal Imaging, IR ShuttersWe design custom NUC (non-uniformity correction) infrared shutters for uncooled and cooled IR (Infrared imaging) camera systems for FPA (focal plane array), Bolometer arrays, and IR image sensor calibration. Brandstrom NUC shutters are found in many high performance thermal imaging cameras, cooled and uncooled, providing internal focal uniformity references. We are currently designing products for next generation technologies.

Both simple and compound microscopes can be used for microbiological studies. Specimens like fungi and algae can be viewed under these microscopes. Microscopes can also be used to study soil particles.

Mechanical shutters function by moving a shutter, vane or filter in front of the aperture or light source, like a laser beam. A electronic shutter relies on image information gathered from a sensor that gathers the data one line at a time.

Microscopeparts and functions

A rotary solenoid actuator is an rotary solenoid but with an attachment other than a shutter meant to move another device in the system.

Eyepiecemicroscope function

Instead of light, these microscopes use beams of electrons to generate images. The two well-known electron microscopes are:

Aviation/Aerospace SystemsThe aviation operational environment demands the employment of multiple technologies all assimilated into cohesive mission equipment packages for both manned and unmanned systems. Brandstrom Instruments offers aviation system shutter solutions for integration into the full range of thermal imaging, multi spectral, laser transmitter, laser ranger finder and laser designator applications.

Nosepiecemicroscope function

Mechanical optical shutters have a wide range of applications and can provide fast transition times to achieve light blocking, light filtering, and light deflecting solutions. Our custom shutters are solenoid driven which provides for highly accurate and reliable aperture control.

A compound microscope is a high-power microscope that has higher magnification levels than a low-power or dissection microscope. It is used to examine tiny specimens like cell structures that cannot be viewed at lower magnification levels. A compound microscope is made up of both structural and optical components. The 3 basic structural components are – the head, arm and base.

Brandstrom Instruments manufactures miniature rotary solenoid shutters, for thermal imaging, laser, aerospace, and scientific applications, that are designed to meet your critical performance specifications. Our solenoids and shutters provide critical performance in some of the most demanding applications, such as:

Stage clipsmicroscope function

Compound and dissection microscopes are the two types of microscopes that are mostly used in schools for educational purposes.

For laser applications we carefully consider the power density and beam size to select the appropriate shutter flag coating, blade angle, or heat dissipating geometry depending on customer requirements.

Spectroscopy & MedicalBrandstrom Instruments’ rotary drive electro-optical shutters are used wherever light paths need to be interrupted in a reliable and precise manner. We have designed shutters for many medical applications including laser eye surgery devices and medical fluid analysis machines.

A bistable solenoid refers to a 2-state solenoid that changes state from position 1 to position 2 when a 50-100ms pulse of positive power is applied. It then remains magnetically latched until a reverse (negative) 50-100ms pulse is applied to return it back from position 2 to position 1.

Brandstrom offers a line of shutter blades to meet the requirements of the most common optical applications. This product selector lets you view the Brandstrom product line with the options you want.

Ground VehiclesBrandstrom Instruments has already fielded thousands of shutters for the Check 6 320 x 240 situational awareness thermal imaging camera in use on the Bradley Fighting Vehicle, and the DVE on the M1, Bradley, Stryker, Mine Resistant Ambush Protected (MRAP) and tactical wheeled vehicles. The robustness of our thermal imaging shutter has been demonstrated in the dynamic and harsh battlefield operating environments of these vehicles.

The basic objective of a microscope is to magnify small objects. More than magnification, the most important function of a microscope is to provide resolution. It should render high-quality details of the desired specimen in order to proceed with the experiment and analysis. Simple and compound are some of the earliest known microscopes that have been recently replaced by electron and fluorescent microscopes. The different types of microscopes are as follows:

The ocular or eyepiece is what an observer looks through and is present in the upper portion of the microscope. The eyepiecetube clasps the eyepieces which are positioned above the objective lens. The objective lenses are the main optical lenses. They range in various magnifications from 4x to 100x and generally include 3 to 5 lenses on a single microscope. Nosepiece houses the objective lenses.

This is a rotary solenoid that changes state from position 1 to position 2 when power is applied and remains in the secondary position until power is removed to return back to position 1.

As a result of technical advancements, one can also find more efficient microscopes like scanning probe microscopes and scanning acoustic microscopes.

A simple microscope is a basic light microscope that has only one lens. The condenser part is absent in simple microscopes. They work on natural light and there is less usage of hooks and knobs for adjustments. On the other hand, compound microscopes have 2 adjustment knobs – fine and coarse. Their magnification is also higher than the simple microscope.

The fine and coarse focus knobs are the adjustment knobs that are often used to focus the microscope. They are coaxial knobs. This means the focusing system of both fine and coarse focus are mounted on the same axis. There is also a condenser focus knob which moves the condenser up or down to control the lighting

Capacity for Volume: Since we are vertically integrated, we have the ability to adjust production of small rotary solenoids to accommodate prototype quantities to tens of thousands of units. Brandstrom is your one stop solution!

Compoundmicroscopeparts and functions

The primary function of a microscope is to study biological specimens. A microscope solely functions on two concepts – magnification and resolution. Magnification is simply the ability of the microscope to enlarge the image. Whereas the ability to analyse minute details depends on the resolution.

An illuminator acts as the light source and is typically located at the microscope’s base. Most light microscopes operate on halogen bulbs with low voltage and also have variable and continuous lighting control within the base. A condenser is typically used to gather and focus the illuminator’s light onto the specimen. It is found beneath the stage and is often observed in conjunction with a diaphragm or iris. Iris or Diaphragm regulates the amount of light that reaches the specimen. It is situated above the condenser but beneath the stage.

There are rotary drive, iris and guillotine shutters to name a few. Brandstrom Instruments is a manufacturer of rotary solenoid optical shutters.

Objective lensmicroscope function

The stage is where the specimen to be viewed is placed. A mechanical stage is often used when working on a specimen at a higher magnification. This is when delicate movement of the specimen is required. Stage clips are operated to hold the slide in place. To see different areas of the specimen, the observer must physically move the slide. A separate knob is present to move the slide in the mechanical stage. The aperture is a tiny hole in the stage via which the transmitted light enters the stage.

ScientificLaser systems often require blocking devices to avoid injury from accidental exposure. Our rotary solenoid shutters are frequently used in safety applications but are also used to redirect, filter or attenuate laser light. We offer reflective finishes, innovative blade shapes, hall effect sensors, ND filters and many more features not found in off-the-shelf products. Our rotary drive shutters are used in commercial, scientific, medical and defense laser applications.

A solenoid actuator works on the same principle as all other solenoids, but with an attachment other than a shutter meant to perform work. See solenoids in action.
