The cubes have a (6-32?) threaded part. The illuminator should have a black screw/knob on the side for this but commodity screws can be used if its missing. Thread the screw in and gently pull the cube out.

Notes for calibrating CNC microscope to get optimal images and maximum light output

First read "BH2-UMA Universal Veritcal Illuminator Instruction Manual". It details the following alignments:
* Centering light source (pg 21)
** With and without centering screen
** Centering screen enlarges image to make it a little easier
* Centering field iris diaphragm (pg 22)
* Adjusting field iris diaphragm (pg 23)
* Adjusting aperature iris diaphragm (pg 23)

Setup:
* BH2-TR30 observation tube
* LH50A lamphouse
* Mitutoyo M Plan Apo objectives
* Special issue microscope body
* Custom built stage

Adjustments / degredation sources:
* Lamphouse can be rolled by loosening screw on side and turning it
* Lamp can be moved a in/out by turning screw on side
* Lamp can be moved a little more in/out by loosening screw on side
* Lamp can be tilted up/down by loosening screw on side
* Objective can be misaligned if rail is not in entirely
* DIC prisms can cause misalignment based on collet position
* Stage can be uneven for variety of machined surfaces not being tight
* BH2-UMA may not be aligned to observation tube...issue?
* BH2-UMA may not be centered from the two setscrews on the sides
* BH2-UMA has pinhole centering screws
* BH2-UMA has iris centering screws
* Cube misalignment/issues?
* Prism misalignment in observation tube?
* Camera not stable in observation tube
* BH2-UMA to observation tube misalignment
* Wrong lamphouse bulb
* Dirty objective
* Broken objective
* Ensure cube fully engaged
* Dirty cube
* Broken lamphouse IR filter
* Polarizers installed when not needed
* Observation tube camera/eyepiece slider not on position
* Sample is uneven

Olympus Turret

2018-12-26T12:12:20Z

Test:

[[Category:Olympus]]

= BH, BH2 =

These use the same horizontal linear dovetail turret:

[[File:mcmaster_microscope_olympus_bh2-4nre_bottom.jpg|200 px]]

However, be warned that BH (always?) uses 25 mm (M25) Neo finite objective where as BH2 uses 26 mm (M26) infinity corrected objectives. Here is the underside of a M25 turret, note that they both look the same:

[[File:zoidberg_bh_neo_turret.jpg|200 px]]

From what I understand, the 25 mm objectives will fit into a 26 mm turret but 26 mm objectives do not fit into a 25 mm turret. Here is a 26 mm turret:

[[File:mcmaster_microscope_olympus_bh2-4nre_top.jpg|200 px]]

There are also RMS turrets:

[[File:mcmaster_microscope_olympus_bh2-5mre_top.jpg|200 px]]

for which you can get plenty of finite objectives and even some infinity such as for MSPlan. Note that all of the RMS turrets are BF while most, but not all, of the M25/M26 turrets are BF/DF.

= BH3 =

[[File:mcmaster_microscope_olympus_bh3-nre5_back.jpg|300 px]]

Unlike earlier BH, the BH3 is motorized and uses a larger vertical linear dovetail. I was able to take the 5 position revolving part off of this and transplant it onto BH2 dovetail to make a BH2 compatible.

[[File:microscope_olympus_bh2_lamp_comparison_cimg1792.jpg|300 px]]

The LH-50A and what I think is the BH2-MLSH45/50 look very similar. The main difference is the illuminator diameter which is much larger on the LH-50A. The LH-50A actually says LH-50A on it (upper left on second picture, hard to see above) and the other has no model listed on it.

Others:
* BH2-HLSH45/100 ("100W Halogen Lamp Housing"): much larger and white
* BH2-LSRF ("Fluoresence Lamp Housing"): requires BH3-UET8 extension tube designed for BH3-MJL bulb holder
* BH3-MJLT: different construction than others. Requires "BHS-LSH50 for 8" arm and the BH3-LSH50-10 for for 10" arm"

I've also seen reference to BH2-ULSH80

[[Category:Olympus]]

The BH2 and BH3 are very similiar and so have been combined to the same page.
Basically, the BH3 adds motorized turret while keeping the same objectives, observation tube, etc.
Many of its parts use BH2 rather than BH3 prefix.
Thus, most of the parts are interchangable.

''' FIXME: mercury burner. Requires special power supply and HCL collector lens
* [[BH2-RFCA]]: "Fluorescence Illuminator, including UV Protective Shield, Immersion Oil 50cc and Dust Cover B071"
''' similar in purpose to BH2-UMA, may even take compatible cubes. Much less common
''' My guess is that this was pre-BH2-UMA flouresence option. BH2-UMA combined all illuminators
''' Might be intended to be used with [[BHS-RFC]] microscope
* [[BH2-RLA]]: BF/DF unit?
* [[BH2-BHA]]: BF only unit?

The illuminator filter assemblies seem to be compatible (or at least fit) between a number of models. I took my beat up BH2-RLA and was able to swap parts to a BH2-BHA.

= BH series =

The BH2 and BH3 are mostly the same with the addition of the BH3's motorized turret. BH parts are generally mecanically compatible but optically incompatible with BH2/BH3 due to the move from finite to inifinity optics. This includes but is not limited to the objective, illuminator, and eyepieces. If you try to mix them your image quality will degrade.

Ex: the BH RMS nosepiece can be used with finite objectives on the BH and used with MSPlan infinity corrected objectives on the BH2/3. Thus, while the part is mechanicly compatible the optics aren't.
