A portrait can depict someone’s appearance and personality in a way no other art form can. It can be the most special of gifts; something the recipient will treasure forever and pass on to their children. If you have never commissioned a portrait before it can seem quite daunting, but great preparation and a great relationship with your portrait artist will assure its success.
New gift ideas for the ones you love can be difficult. You may have been with them for many years and have achieved the financial success that means you can have any physical possession you both want. Finding something truly unique can be really difficult. Yes, you can have something engraved or embroidered, but that only adds a limited element of uniqueness to your gift.
The optical collimator makes the reflex sight possible. The collimator aligns a stream of particles from a source into a parallel stream. The collimator is either refractive or reflective. An image of the reticle, generated by the collimator and illuminated by a fiber-optic or radioactive light source or LED, is projected to infinity. This image is directed onto a dichroic mirror or beam splitter which uses a special reflective coating so as to reflect only the exact colour of the reticle whilst allowing all other colours to pass through. This produces a perfect image of the target with the aiming mark projected to infinity.
Reflex or ‘red dot’ sights have become extremely popular with civilian shooters and are now ubiquitous throughout Western militaries. Three companies have taken the lead and now dominate this sphere; each has a different approach to the task of rapidly engaging and hitting targets at short to medium ranges.
I was 44 years old, passably fit and quite active. I had an office job at the NHS, but a reasonably active life outside of that, spending as much time as I could walking the hills or exploring the cold clear waters of the North Sea. Constipation was something that happened to old people – not me. Life was good, but things were about to change.
