Most color blind people who take the new color blind test while wearing EnChroma glasses see improvements to their defective cone scores.

A translation stage with a motor is a precision mechanical device used in motion control applications that allows for precise linear movement along single or multiple axes. The motor is used to drive the translation stage, providing smooth and precise motion control. Translation stages with a motor are commonly used in scientific research, bio-medical, life sciences, metrology, semiconductor, precise manufacturing, and other industries where precise positioning is required.

At Dover Motion, we specialize in designing and manufacturing motorized optical stages that meet the highest standards of accuracy and reliability. Our stages are designed to deliver smooth, stable motion with sub-micron positioning accuracy, even in harsh environments or challenging applications. They range from single-axis stages for simple applications to multi-axis systems for complex processes and are available in a variety of sizes and configurations, with options for linear or rotary motion. Our experienced team of engineers works closely with our customers to understand their specific requirements and design custom motorized optical stages that are tailored to their unique needs.

Linear motor stages offer higher speed and precision, while screw-driven stages are more cost-effective and suitable for less demanding applications.

Our screw driven motorized stages range from stages with monolithic integrated XY centers to low-cost, single axis stages with crossed roller ways and stepper motors.

EnChroma has taken color blind testing to the next level. Unlike old and outdated Ishihara tests developed back in 1917, our new color blind test uses the science of cone isolation to test the sensitivity of each of your eye’s three color-sensing cones and scores them to show you how close or far you are from having normal color vision. And, unlike any other color blind tests on the internet, our new color blind test can be taken while wearing EnChroma color blind glasses so you can compare your before and after results to see the improvement in your color vision deficiency.

Drive Mechanism: The drive mechanism transmits the motion from the motor to the stage platform. It can be a screw drive, belt drive, or direct drive system.

A motorized optical stage is a stage that is designed for use with optical instruments such as microscopes or cameras and is moved by a motor. It provides precise control over the position and movement of samples and optical components. The motorized optical stage has higher precision and accuracy requirements than the general motorized stage, as the movement of the sample or component needs to be very precise for accurate imaging or analysis. Some motorized optical stages have additional features such as encoder feedback for closed-loop control, joystick or computer control, and programmable motion profiles, which are specific to optical applications.

Once the payload has been constrained to a single degree of freedom, the system’s next mission is to actuate the payload and provide precise incremental linear motion along the guideway.

If you score 0% on one of your cones both with and without the glasses, the chances are very high that you are a dichromat. This is a relatively rare form of colorblindness, where one cone type is completely missing. Dichromats generally do not see color enhancement when wearing EnChroma glasses.

Controller: The controller is responsible for controlling the motor's speed, acceleration, and position. It receives input signals from sensors and actuators and generates appropriate control signals to achieve the desired motion.

Our direct drive linear motor stages include linear servo motors and offer higher speed, acceleration, and accuracy than belt-drive, lead screw, or rack and pinion actuators.

Scoring 0% means you did not answer correctly on any of the test images targeting that cone. It does not mean that you can’t see that color at all; rather, it just means that you have a strong defect in that cone.

Our Z stages offering includes traditional Z stages for objective focusing and Z stages for sample positioning or Z-Lift stages .

Motor: The motor is the driving force behind the stage's movement. It converts electrical energy into mechanical energy to move the stage platform.

The motorized stage provides precise automated positioning and is available in single or multi-axis architectures. It is also commonly referred to as a motorized table or motorized actuator.  Each axis of a motorized stage must constrain the six degrees of freedom (X, Y, Z, roll, pitch, and yaw) of the payload to only one, producing automation along a single axis of motion. This is accomplished with a set of linear bearings, which are mounted to a metal base to provide a stiff structure.  Our stages designed specifically for vertical motion can be viewed on our Z Stages page.

EnChroma glasses for color blindness are uniquely engineered to give those with color blindness the ability to see more of the broad spectrum of bright color most of us take for granted. Utilizing a patented light filter technique, our lens technology is applied with mathematical precision to address common forms of red-green color blindness.

Scoring less than 100% on more than one cone does not mean that you have more than one defective cone. Your defective cone is the one that you score lowest on. Sometimes, people also score below 100% on their non-defective cones. This is related to how the brain processes color by combining the signals from different cones, which in some cases can make it more difficult to see images targeting a non-defective cone as well. Additionally, the blue cone can lose sensitivity as we age, leading to lowered scores.

Sensors: Sensors are used to measure the stage's position, velocity, and acceleration. They provide feedback to the controller, allowing it to maintain precise control over the stage's movement.

The Ishihara test, the old EnChroma test, and other online color vision tests were developed only as broad color vision screening assessments and did not use cone-specific colors. Therefore, they cannot show improvement to the individual cones. Only the new EnChroma Color Blind Test can show this improvement.

Other products on the market might help on the test, but none use EnChroma’s patented lens technology, instead manipulating relative lightness of colors. EnChroma lenses increase the color contrast in the image, improving your ability to see the cone-isolated hidden symbol. These other lenses may or may not help your test scores but they won’t really help you see true colors.

The new test gives much more specific results for each cone, instead of broad categories like mild, moderate, and severe. Your score on your defective cone (red cone if you’re a protan, green cone if you’re a deutan, blue cone if you’re a tritan) is a measure of severity: the lower the score, the more severe your colorblindness.

Some score variability is to be expected, but if you get very different results on different devices, check if you have any color filtering effects turned on, such as blue-light filtering or color blindness assistive apps. These can significantly impact your scores. For the most accurate results, use the newest device you have access to.

Our microscope stages are made with embedded high-performance precision electronics required to control motion within the stage without increasing its size.

A motorized stage is a high-performance positioning system that utilizes integrated motors to drive a platform with exceptional accuracy along one or more linear axes. These stages are instrumental in various automated applications across science and industry, particularly those requiring meticulous object manipulation.

The cone score percentages shown as part of our new test vary by up to +/-13% for most people, so your cone scores could change within that range when taking the test multiple times. If your scores vary by more than that, other factors may be affecting it such as screen brightness or using different devices.

Sometimes, in addition to seeing increased scores for their defective cone, people see a slight decrease to their non-defective cone scores while wearing the glasses. This is normal and does not indicate that you have the wrong lens for your colorblindness. You won’t notice this effect when wearing the glasses out in the real world.

Using a linear motor is generally considered to be optimal for high speed motion systems and is the most precise and repeatable linear motion actuation technology.

A motorized stage with a linear motor requires a linear feedback device as well as a servo drive and control to close a position feedback loop. With a high-resolution linear encoder, linear actuators can provide position control down to the nanometer level. A typical application for high precision linear actuators is to control the focus of a microscope objective in a digital imaging system.

The SmartStage™ XY motorized stage features a built-in motion controller, ONE external cable and has a 5 nm resolution with 0.8 um bi-directional repeatability.

Our XY tables include high performance, open frame, monolithic high load, and custom designed XY tables that move in two degrees of freedom and offer high precision and efficiency for digital imaging applications.
