This was removed from a working Zeiss microdissection microscope.
It is functional and looks clean.  
The filter is 50mm in diameter. 
This should be an ND filter, reflective type.  Correct me if I am wrong. 
It is installed with a motor and ready to be used for your setup.

Shipping:
Shipping costs adjusted for travel, materials and handling.  Read this carefully if you are from the USA or Germany.
I ship globally.  Will combine postage.
Sometimes, eBay does not combine postage costs.  Pay anyway and I will refund the difference, or wait for an invoice.  I can also do custom listings.
AusPost Standard: Most regions
AusPost Express: Middle East, some parts of Asia, Africa, South America.  Standard offered if you are willing to accept slow delivery time.
AusPost Parcel Post to anywhere in Australia. 
Usually ships in a day, however, I do get busy at times and go on business trips, so please allow up to 7 days.
USA: My items are shipped DDP (delivered, duty paid).  You do not need to worry about the tariffs, I am paying for them.  However, the tariff cost is built into shipping, so you are paying for them, contrary to what someone who turned Texas blue would claim.  You will still have to pay the goods tax, if applicable (OR, FL and NH does not have a goods tax).  Thank Donald Trump for this.  Once the mess ends, I will revert back to my old rates.  Your big companies will not.
Germany: From 1st Nov, 2026, Germany now requires the seller to pay for both the VAT (19%) and handling cost (around 11 euros).  
There are two options:
1. I will send it via FedEx.  You will pay for VAT as usual.
2. I can send with AusPost, DDP (delivered, duty paid) only.  I will pay for VAT and handling cost.  However, you must wait for an invoice.  This amount will be passed onto you fully.  You will pay 20% more because I must account for eBay fees (around 20%).
I do not know why your government is doing this.  Many German sellers are now refusing to ship to their own country.


Returns and refunds:
Accepted if the item is not as described.  Full refund in case it is lost or damaged.  High value items will be insured. 

Customs: 
It is the buyer's duty to contact customs in case of items being held for clearance.  I will provide invoice upon request.  
An item held for too long will be returned.  I will not refund postage in this case. 
It is the buyer's duty to contact me regarding any special customs provisions the destination may have.
