Leica DMi8 Inverted Microscope Overview
(Final microscope capabilities will depend on the modifications you request)
- Modular inverted research microscope supporting brightfield, fluorescence, THUNDER computational clearing, and AFC focus stabilization.
- Fully motorized platform with automated control of XY stage, condenser, objective turret, and fluorescence components.
- Leica HC Plan Fluotar optics provide high contrast, high resolution, and excellent fluorescence transmission.
- Integrated LED fluorescence illumination with Lumencor light engine and motorized multi-position filter cube turret.
- Precision scanning stage enables accurate sample positioning for automated imaging and large-area acquisitions.
- THUNDER technology enhances widefield fluorescence images, while Adaptive Focus Control maintains stable focus.
THUNDER Imaging Technology Benefits:
- Computational Clearing for Improved Image Contrast
THUNDER uses Leica’s Computational Clearing (CC) technology to reduce out-of-focus background in widefield fluorescence images.
Benefit: Produces sharper, higher-contrast images from thick samples such as tissue sections, organoids, and 3D cell cultures.
- Real-Time Image Enhancement
THUNDER processes images during acquisition using advanced computational algorithms integrated with the LAS X platform.
Benefit: Researchers can view enhanced images immediately without extensive post-processing.
- Improved Visualization of Thick Specimens
The system improves optical sectioning in widefield fluorescence microscopy by reducing haze from out-of-focus light.
Benefit: Better visualization of cellular structures within thicker biological samples.
- Enhanced Z-Stack Imaging
THUNDER improves the clarity of z-stack acquisitions by computationally suppressing background fluorescence.
Benefit: More detailed visualization of 3D biological structures and layered samples.
- Improved Signal Detection
Computational clearing enhances signal-to-background contrast, helping reveal weak fluorescence signals.
Benefit: Enables clearer detection of subtle or low-intensity fluorophores.
- Optimized for Live-Cell and High-Speed Imaging
Because THUNDER operates with widefield illumination rather than scanning optics, imaging can be performed quickly with minimal phototoxicity.
Benefit: Well suited for live-cell imaging and high-throughput fluorescence workflows.

How do you pack? Have you previously packed and shipped a Leica DMi8 Inverted Microscope? Do you ship Internationally?
Packing
- Smaller microscopes ship via UPS Parcel Delivery with adequate packing material and a strong box. Or, when combined with other orders, it may be packed in a crate.
- Most larger microscopes ship in fully enclosed ISPM15-certified wooden crates with proper padding underneath, and the sides have moving components braced.
- Accessories are packed safely in boxes with padding and then safely packed inside the crate.
- We may not use a crate for local deliveries to save you money *if delivered by us.
- We often use “tilt’ & “shock” indicators on the crates to ensure the crate has not been excessively tilted and dropped where equipment may suffer damage.
- Photos are taken during the packing process to make sure nothing is missed.
USA/Canada Shipping
- Within the US and Canada, we will ship via selected freight carriers. We do not use low-price/high-damage carriers as we want the equipment to get safely to you.
International Shipping
- Internationally, we will only ship via Air Freight or Air Parcel (such as UPS or DHL), which provides reliability, no exposure to Ocean weather, and timely delivery.
We have extensive experience packing and shipping fragile microscopes globally.
Our experience and process
- We have safely packed and shipped thousands of sensitive analytical instruments.
How much will I save buying it pre-owned, and is it worth it?
A lot…and it is undoubtedly worth it, and here is why. Feel free to ask for feedback from hundreds of customers who bought from us.
- When compared to buying a new one, you will save up to 60% to 80% and have plenty of funds left over for an additional instrument or two.
- You will get our standard warranty, plus, when available, an option to obtain an extended warranty agreement.
- Know that your microscope was tested and working the day it left our facility and is covered if there are faults.
Sustainability
- Well, this one is easy: buying a pre-owned microscope is great for the planet; you are reducing unnecessary waste, CO2 output, and water use that would be used during the manufacturing process.
