Lighting Systems

A genuine fibre optic system with a powerful 10 watt LED light unit delivering dual spot lights via two goose neck fibre optic arms. The unit is shown here attached to its circular heavy duty base that provides excellent stability as a stand alone unit. However the unit comes complete with a simple adapter that will allow the power box and goose necks to be attached to the upright of most stereo pole stands. This allows the fibre feeds to be positioned to give optimal illumination for the specimen being examined without the support base ‘getting in the way’. The unit has an excellent fan cooling system and a rheostat brightness control.

An excellent double flexi arm light unit. This is not fibre optics but a bright LED unit attached to the end of each arm. At full rheostat control the light is comparable to a 100 watt fibre optic unit for a fraction of the price. Recommended

the Brunel LED78 has a brushed steel ring with 78 concentric LED's. Powered by a stand alone transformer with full brightness control. Adapters are included for the IMXZ, BMS, BMZ and BSR stereomicroscopes.

An excellent spot light ideal for stereomicroscopes. Flexible arm allows positioning to suit the specimen. Rheostat controlled for variable lighting power.

A 240v fluorescent ring light that gives excellent vertical illumination. A budget alternative to fibre optic ring lights at a fraction of the cost.

An LED ringlight that fits the Brunel Microzoom. Rheostat controlled illumination.

This is a particularly compact LED ring light that does not need an independent transformer unit. All the electronics are housed within the unit itself which simply plugs directly into the mains electricity supply. The ring light has 60 individual LED's arranged in two concentric rings. There is a toggle on/off switch with rheostat brightness control. Colour temperature 6000K. The Compact LED will clamp to the bottom of any stereohead with parallel sides up to a maximum diameter of 60mm. The unit will fit all the stereoheads in the Brunel range irrespective of their shape as appropriate adapters would be supplied.

This is a dual ring light with two concentric rings of LED's. The outer ring of 39 LED's provides white light 6500K illumination and the inner ring of 39 LED's provides ultra violet (365nm) lighting. Both rings can be used independently or if required together. Each ring has a separate on/of and brightness control to the front of the power box which itself has an illuminated on/off button. The unit will fit all the zoom stereoheads of the Brunel range and may fit other makes providing the microscope head has parallel sides and is a diameter no larger than 60mm.

A unique unit available only from Brunel Microscopes Ltd.

Our Dual light LED unit is quite simply one of our best new products in recent years. We have now introduced a more specialised version with the dual arms delivering white light 6500K from one arm and UV light (429nm) from the other arm. This is not a fibre optic unit but two very effective LED light units mounted on goose neck flexible arms. The l white light output is outstanding and would match a 100 watt fibre optic unit at full capacity. Finished in black enamel the metal alloy base is very stable and has an on/off switch with full rheostat control for each of the arms. These can be used together or separately. The flexible arms have good rigidity and maintain position well. As with all LED units the heat gain is minimal and therefore ideal for heat sensitive specimens such as insects. This lighting system is highly recommended.

The image detail with stereomicroscopes depends largely on the type and direction of lighting. Ringlights tend to produce ‘flat’ images with minimal shadows because the light is directly above the specimen. Goose neck LED and fibre optic systems however can be angled as required to produce shadows and therefore add to the 3D effect of the image. The Duo light unit allows the best of both worlds with a single goose neck with rheostat brightness control and a ringlight with 60 individual LED’s in two concentric rings with brightness control. All at a very reasonable price.

This stand alone unit is ideal for providing transmitted illumination away from the more traditional light base stands of stereomicroscopes. Particularly recommended for our range of long arm stereomicroscopes. The unit consists of a circular light base with the light area measuring 90mm with a translucent surface that give a very even field illumination. Internal LED light source which is powered by a separate transformer box.

An LED light source with a double goose neck light guide. Full rheostat control and excellent quiet cooling fan. Highly recommended.
