▪ Is it plugged in? This should be the first thing you check.
▪ Is there light coming from the bulb? If not it, try replacing it.
▪ Are the fuses blown? Replace the fuses if they are easily accessible
▪ Call or email us if none of the above steps fixes your problem

▪ Refer to the scope’s instruction manual if possible
▪ Unplug the microscope. Do not skip this step.
▪ Microscope sockets are often accessed at the rear or underneath the microscope
▪ After removing the old bulb, avoid is touching your fingers to the glass of the new bulb while plugging in to the socket
▪ If you do touch the glass, wipe it clean with an alcohol swab before turning it on
▪ Some bulbs, like the mercury ones used in fluorescence, may require alignment, and we recommend getting a qualified service technician for this kind of bulb change

▪ You may have the wrong type of bulb, this is the most common cause of this problem.
▪ The socket may need to be replaced
▪ Sometimes powerboards or variable resistors fail

▪ The type of bulb should be displayed on the rear of the scope or on the socket
▪ 6V20W are common for older scopes, student scopes, and some clinical scopes
▪ 6V30W are common in newer scopes, clinical scopes, and some research scopes
▪ 12V100W are common in clinical, multi-headed, and research microscopes
▪ There are other common bulbs, but these three are the most common
▪ Call or email if you are unclear about which type of bulb you need, the wrong bulb may not get bright enough or burn out immediately

▪ If there is oil used on the scope, it could be on the objective
▪ KOH or Urine may have delaminated the optical coating on your objective
▪ Dust in the optical path
▪ Eyepieces get filthy over time
▪ There are many other possible reasons

▪ Try to keep oil off of the non-oil objectives
▪ Clean excess oil / urine / blood / KOH / whatever off the stage
▪ Cover the microscope when not being used to keep dust off
▪ Set up a scheduled maintenance plan with us to maximize the life and utility of the scope

▪ Objectives can range in quality and can be upgraded
▪ Eyepieces can be changed as well
▪ We recommend checking compatibility before ordering eyepieces or objectives for your microscope
▪ Call or email for inquiries about optical upgrades

▪ We will take certain microscopes, objectives, cameras, etc. for credit
▪ Email for a quote

▪ Yes, we offer several options for camera addons depending on your application and price range
Email for options

▪ You may be experiencing a double image
▪ This may be fixed by adjusting the diopters on the microscope
▪ This can be adjusted during a service but sometimes requires a repair

▪ Older microscopes have a tendency to seize up
▪ This usually requires an overhaul
▪ Commonly overhauled parts include the focus, stage, nosepiece, binoc, and variable resistor
