Abstract: A loupe support system includes a frame (12) which can be mounted at the head of a user and at which a holding device (18) is mounted, an elongated support element (30, 31, 68) which, at its central region, is supported at the holding device (18) such that it can rotate about its longitudinal central axis, wherein a respective loupe ocular (34) is mounted at the support element (30, 31, 68) on each of both sides of the holding device, and a light mounting element (22) supported at the holding device (18) such that it can rotate about a rotary axis being coaxial with respect to the longitudinal central axis of the support element (30, 31, 68).

Abstract: A head band for diagnostic instruments comprising a light source and a battery has, at its back support part (12), a flat housing (21) for adjusting and fixing the head band length by means of a rotary knob (22). An accumulator module (31) optimized with regard to volume, weight and weight distribution can be mounted and detached by means of bayonet-type grooves (25) at the housing (21) and pins (33) at the accumulator module (31), and can be fixed by means of a resilient spring (26) at the housing (21) and a recess (34) in the accumulator module (31) without impairing the function of the rotary knob (22).

Abstract: A battery grip for diagnostic units comprises a grip sleeve for accommodating batteries, at the upper end of which a metal sleeve for accommodating a consumer load, such as an electric bulb, is mounted, a guide opening formed in the wall of the grip sleeve, a switching slide being guided the guide opening in a longitudinal direction of the grip sleeve, a contact member extending from a lower end of the grip sleeve with one contact end into the guide opening, and a contact spring member having one end conductively connected to the metal sleeve manner and another free end extending into the guide opening such that the free end is disposed above the contact member and is brought into contact with the contact member by displacing the switching slide. The contact between free end of the contact spring member and the contact member is created by at least two contact points. At least one longitudinal recess is provided in the contact end of the contact member.

Abstract: A headband apparatus for head-worn optical instruments includes a headband (12) and a bow (16) on which the optical instrument is fitted, and which is fitted with both its ends (100) to the middle region of the headband (12) such that it can swivel about a swivel axis (S) between a working position and a rest position. Fastening elements (26, 28) for releasably fastening additional elements (38) are fitted on the headband (12).

Abstract: An ophthalmoscope includes a housing (12) in which there are arranged an observing unit and a light source between which there are/is arranged a diaphragm and/or a filter device that can be set via a swivel lever device (16, 17) mounted outside on the housing (12). The swivel lever device (16, 17) can be locked in respective latch stages by a locking device (41).

The contact between free end of the contact spring member and the contact member is created by at least two contact points. At least one longitudinal recess is provided in the contact end of the contact member.

Abstract: A power source device for diagnostic instruments is adapted for a connection of different types of illuminating devices and includes an active control unit for controlling an operating state of a power source in dependence on a type of a connected one of the illuminating devices.

Abstract: An illuminating apparatus for handheld or headworn instruments comprises a luminous means (50), a heat sink (42) for dissipating heat produced by the luminous means (50), and a ventilation device (57), fitted on the heat sink (42), for feeding cooling air to the heat sink (42). A damping device (60) for damping the oscillations generated by the ventilation device (57) is provided between the heat sink (42) and the ventilation device (57).
