  • Loupe advice needed.

    Sigh, getting old's not for wusses. I have various magnifying devices, a fold down visor, flourescent ring light with magnifying lense, etc but after using box of cheap plastic loupes off of ebay I want to go ahead & get a decent one.

    Which type & power would be best for looking at stuff like carbide insert tips & the like. The cheapo plastic one at 10X helps a lot but obviously there must be better ones out there. Triplet or Coddington style lense?

      Look at "otoscopes" on ebay/amazon (dirt cheap to damn expensive) I have several. Perfect for looking at the tips of tooling, inside carburetors etc. Hey, even good for what they were originally designed for.. looking in ears, up noses and for machinists -at slivers in fingers.

        I use the long focal length surgical visor myself, focus at about 450mm, not to close to spinny mangly things, found optivisors crap myself, short focus

          Hi Dickybird I use an Optivisor 5x magnification for general work and have an 8x lens as well, you can also get an attachment that folds over one eye for occasional extra power.
          These have high quality optics, far better than most and I find them the best I have used, got mine from Brownells.
          Cheers John

            I also have the Optivisors, some three pair, but lately have taken an interest in those binocular thingies that
            the dentist, and surgeons, use. Have no idea how they would be in practice but they are quite popular
            with the medical set. I'm sure they are quite spendy. I have a couple of hand loupes up to I think 10x for
            really getting in close. The one I like best is fully anchromatic (I don't know what that lens stack is called)
            and give good wide field view.

              I have Optivisors and various loupes plus several high quality inspection lenses. They all have their purpose but I find that when I use the loupes, the biggest problem is getting light on the object being inspected. Recently I bought one of these...

              http://www.amazon.com/gp/product/B00...ilpage_o01_s00

              and I love it. The LEDs provide brilliant white light on the subject and the lens is high quality. The viewing window has built in inch and millimeter scales but, more importantly, placing it on the subject sets the lens at exactly the right focal distance.

                Deal Extreme or some other Chinese merchants sell a 30X illuminated loupe that is very good. I think it costs about $10.00. I have a couple of them around the house. Be advised that the focal length is pretty short, but the concentrated light is a great help.

                  They arent the cheap solution but if you need to see, they work.
                  Dont think dentists and surgeons whant to stick thier face in sombodys orifices!, try one you will be suprised, for one thing you can work at arms length, much easier

                    The real stuff used by dentist etc start at a couple of grand... I asked my dental assistant how much hers cost. frigg... I have a Pakistani version for $60... not superb, crappy frames, but they work well enough so I can (carefully) run my lathe while wearing them.. lol

                    I have about 10 different thingies for looking at stuff close up... nothing works "best" for everything.

                      Crazy idea.

                      Since a willingness to spend some money is detected,
                      what about adapting a digital microscope to display
                      on a monitor ?

                      High resolution, as large a display as your budget allows,
                      as much distance from chips and whirly bits as you wish,
                      photo and video image capture ready. Magnification
                      starting at 10 and going up .

                      I have an inexpensive jewelers loupe (India), a Magna Visor
                      (Bausch & Lombe) and a vintage Champion Spark Plug light;
                      plus some magnifying glasses. All for static use, not while
                      machines are in use.

                        Had a procedure done a few weeks ago. The doc let me look through his Zeiss unit which has its own light and can change focal length out to around 2 ft. The view was amazing. So was the price. The entire setup, including a super smooth articulating arm cost him $35,000!

                          I've recently thought about how well a vid camera would work for little parts work on the lathe. Something where
                          the camera was mounted out of the normal sight line but close enough that the view wasn't so different to be
                          confusing. A monitor on the back splash would be convenient I think. Then there would be the normal view and
                          a magnified view on the screen. The camera could be put into positions that would allow seeing things that were
                          difficult to see usually. Like when boring or ID threading.... ?????

                            Realistically, a monitor on my backsplash would have a boatload of curly-burns and oil smears within 30 minutes. Same with any plastic optics nearby.

                              Where's the read-out for your DRO mounted
                              and what is it made of ?
