Battery and Chargerarrow12Battery and Charger

Compact battery pack that can run the Stereo Microscope Fluorescence Adapter (SFA) all day long. The battery enables truly portable operation so that you can set up demos anywhere or explore fluorescence in the field, without having to worry about plugging into the power grid.

Just plug the battery into the SFA base instead of the usual power connector. The battery has been tested at over 8 hours of continuous operation, and it will last even longer if you turn the system off when you don't need it. Plug it into the included charger overnight to recharge.

SFA + Eclipse MicroTent + Battery = Fluorescence Everywhere

Combine the battery with the Eclipse MicroTent and you not only don't need a place to plug in, you don't even need to be in the dark! We have used this combination to do fluorescence microscopy at a beach in the middle of the day, in the desert at high noon, and more. Fluorescence can be found everywhere, and now you have the tools to go there.

The Eclipse MicroTent™ is a unique product for fluorescence microscopy that provides local darkness around conventional laboratory stereo microscopes. Fluorescence microscopes are kept in dark rooms for good reason - fluorescence can be weak and in many cases it can be difficult to see well if there is any ambient light. Microscopes may be on lab benches in shared spaces, near windows, or in other difficult-to-darken locations such as in the field. Turning off overhead lights can help but inconveniences others.

The Eclipse Microtent creates local darkness around a microscope while still providing easy access to the sample stage and the focus and zoom controls. It is designed for stereo microscopes but could potentially be used with many varieties of compound microscopes.

Features

  • Opening for the microscope oculars with elastic sleeve to minimize light entry
  • Large front flap provides easy access to the sample stage and can fasten open
  • Arm slots on sides to provide access to focus and zoom controls
  • User-customizable feedthrough patches to provide additional penetrations for camera port, power cords, CO2 lines, or other features as you need
  • Tru-Block™ Eye Shields included with every Eclipse MicroTent
  • Folds flat for storage
  • Dimensions: 46 x 30 x 50 cm (18 x 12 x 20 in.)

Technical Data SheetEye Shieldsarrow12Eye Shields

Light entering your eyes from the side can interfere with what you want to see in microscopy in general, and fluorescence microscopy in particular. Eye cups are available, but the standard ones don't extend far from the microscope and don't do a good job as ambient light increases. Our soft, molded rubber high-sided microscope eye shields are the answer. The tall wings extend up far enough to truly shield your eyes from any level of ambient light and eliminate distractions so that you can see your subject better. Two pairs (one Standard, one Compact) will be included with every Eclipse MicroTent™, and you can also purchase them separately.

The Tru-Block Eye Shields are available in two sizes:

  • Standard - fits 36 - 45mm (1.45 - 1.75")
  • Compact - fits 28 - 37mm (1.10 - 1.46")

Modular White Light Headarrow12Modular White Light Head

A white light head is also available as an illumination option for the Stereo Microscope Fluorescence Adapter. Now if you are using the NIGHTSEA™ system for fluorescence you do not need a separate light source for your white-light work - just exchange the fluorescence excitation light head module for the white-light module in a matter of seconds. Extremely convenient for general illumination and as a focusing aid for fluorescence imaging.

BNC and V1 Connectorsarrow12NIGHTSEA™ Light Head Connectors

Light Head connectors come in two types. They are not interchangeable. The new style connector is called a BNC, and the original connector is a V1. There are two differences – the connector on the end of the gooseneck and the mating connector on the back of the light head. It is easy to tell them apart:
  • The BNC connector on the gooseneck is silver, while the V1 connector is black
  • The BNC light heads have the letters BNC printed on the side

  • Light Head Hanger, short working distance, highest position
  • Short Arm Light Head Hanger, lowest position
  • Single Light Head Cable, BNC
  • Dual Light Head Cable, BNC

The NIGHTSEA™ light head hangers and cables conveniently hold the light head in lieu of the gooseneck lamp. The hangers mount to the end of any of the thumbscrews on the SFA adapter ring. They are available with two different pivot arm lengths for use with long and short working distance microscopes.

The cables are available in single and dual styles. With the single cable and one light head hanger you can remove the light head from the gooseneck and mount it on the SFA adapter ring. With the dual cable you can power TWO light heads from one base. Just add a second light head and two light head hangers and you have double the excitation intensity.

The light head hangers are offered for microscopes with different working distances below the objectives:

  • Long working distance (LWD) – 6.5 cm (2.56 in.) and greater
  • Short working distance (SWD) – 6.3-4.6 cm (2.48-1.81 in.)

The light head hangers and cables are available individually or in combination kits.

Easily change the lighting conditions while you work with the Switch Box Kit. Available for BNC light heads only, in both working distances (long and short). Kit consists of a BNC switch box, 3 BNC cables (including one with a female to female adapter to attach to the gooseneck), and 2 Light Head Hangers.

arrow11NIGHTSEA™ DIM and PULSE Options

We offer two optional enhancements for the Model SFA Stereo Microscope Fluorescence Adapter - DIM and PULSE. These are available either as a retrofit or as an add-on to a new system purchase.

  • DIM- Replaces the OFF/ON switch with an OFF/ON/DIM switch. This enables you to vary the excitation intensity.
  • PULSE- Adds a BNC connector on the rear of the light base that accepts a voltage signal to control the excitation source ON/OFF.

*Note: Only one of the options can be added to a particular base unit.

arrow12NIGHTSEA DIM Option

The DIM option adds a combined switch and dimmer control. When you first turn the unit on it is at full power. As you rotate the switch the intensity decreases, reaching about 30% power at the minimum setting. You have finer control in the brighter portion of the adjustment range. An intensity indicator (1-10) makes it easy to record and repeat preferred settings.

NIGHTSEA DFP-1 Dual Fluorescent Protein Flashlightarrow12NIGHTSEA™ DFP™ Dual Fluorescent Protein Excitation Flashlights

Rapid screening of your fluorescent transgenic experiments

  • Dual Fluorescent Protein Flashlight
  • Dual Fluorescent Protein Flashlight

The Model DFP Dual Fluorescent Protein Flashlights include two different, switch-selectable high intensity LEDs for excitation of fluorescent proteins. For years the most popular fluorescent colors have been green (GFP, eGFP, fluorescein, etc.) and red (DsRed, TdTomato, etc.), and we offered only one version of the DFP, with a combination of blue and green LEDs for exciting these fluorophores. This is still our 'standard' DFP product, but we are now offering build-to-order combinations using any two of the excitation colors that are available with our popular Model SFA Stereo Microscope Fluorescence Adapter.

With every DFP light you will receive two pairs of barrier filter glasses and a convenient storage case. The glasses are well matched to the excitation so that they block the reflected excitation light while transmitting the fluorescence with high efficiency, providing excellent viewing contrast.
