You may have a keen eye for detail, but if your stereo microscope isn’t adjusted properly your focus may fall short. To be clear, just turn your attention to the following operating tips, and zoom in!

How to Set Up Your Stereo Microscope in 10 Simple Steps

  1. Set your microscope on a flat, stable surface.
  2. Turn on the illumination, and illuminate your subject.
  3. Set the diopter setting(s) to zero.
  4. Adjust the distance between the eyepieces (interpupillary distance) until it’s comfortable and you see a single image.
  5. Adjust the brightness to the desired level.
  6. Zoom up to the highest magnification.
  7. Close your right eye (or the same eyepiece as the diopter adjustment), and adjust the focus until the image is clear.
  8. Close your left eye, and adjust the eyepiece diopter until the image is clear.
  9. Make a note of your diopter setting for future reference.
  10. Enjoy a properly focused microscope.

Following these simple steps will help ensure your sample remains in focus throughout the zoom range.

Down with LEDs: Do Your Lights Lack Focus?

by Kathy S. on August 10, 2015

Down with LEDs--Do Your Lights Lack FocusDo you have a one-track mind? Hey, it works for LEDs. Their “brains” are only the size of a fleck of pepper! LED, or light emitting diode, converts energy into light. But, because it’s a diode the current only flows through it in one direction. If you try to make the current flow in the reverse direction, it won‘t work, and you won’t get any light.

This may sound particularly close-minded of today’s favored light source, but you can use this tunnel vision to your advantage. Conventional light sources cast a lot of light backward and require more reflectors and diffusers that can trap light. More than half of the light may never leave the fixture. Since LEDs emit light in one direction—downward—they are more efficient than incandescent bulbs and CFLs in recessed downlights and task lighting. Pretty smart for a pepper-sized brain!

When it comes to the task at hand, All-Spec carries the LED lighting solutions you need to help keep you on even the narrowest of tracks.

Reverse Action Tweezers--Hold onto This 1-Minute ReviewDoes reverse psychology get you what you want? Sometimes it works, and sometimes it backfires. Not all reverse actions are so touch-and-go. For inspection applications that are more “touch-and-hold” than touch-and-go, reverse action tweezers come in handy.

Reverse action tweezers, also called “negative action” and “cross action” tweezers, are generally used when small items must be held for a minute or longer and not just picked up and placed. Traditional tweezers close and grip objects when you apply pressure and open when you release your grasp. Reverse action tweezers, on the other hand, work the exact opposite way. Their tips are closed when not in use and open when you squeeze them. What’s great about this design is you don’t have to apply continuous pressure in order to maintain your grip.

Also convenient is they feature the same types of tips as standard tweezers.

Save your hand as well as your sanity. Consider All-Spec’s selection of reverse action tweezers; no reverse psychology is needed.

Single- and Dual-Wire Monitors--Which Performs Better Under the Big TopHave you ever compared electronics assembly to tightrope walking? While some days you may feel as though you’ve joined the circus, the common denominator here is—or should be—the beloved safety net. Without it, one misstep and your tightrope performance may fall flat.

What about in the workplace? What happens if an operator’s wrist strap malfunctions? Will your single-wire monitor catch you? With the dual-wire continuous monitor, even if one conductor is severed, you can always fall back on a reliable path-to-ground with the other one.

Single-wire continuous monitors, also known as impedance monitors, are also easily fooled. Great for your tightrope-turned-magic act, but not so great for safeguarding sensitive components. Single-wire monitors send a signal down the wire to the wrist strap expecting to find a mass (a person) at the end of the coil; they cannot determine if a person is actually electrically connected.

Dual-wire continuous monitors or resistance monitors, on the other hand, measure the resistance of the wrist strap in combination with the person, and signal an alarm if the product exceeds preset levels.

For the performance of a lifetime, shop All-Spec. We carry a broad selection of foolproof, dual-wire continuous monitors, so you can rest assured a reliable path-to-ground in just about every situation.

  3. Are you using any solvents as cleaning aids?
  4. What conditions of cleanliness must be maintained?
  5. Will there be considerable abrasion during use?
  6. Are you applying lubricants?
  7. How will swab shape and construction impact your work?
  8. What is your budget?

Then, follow up with our Swab Selection Guide for all the food for thought you need.
